Your fill water is probably having metal in it and apart from clearing the stain, you need to prevent further staining. Answer: Calcium scales come as a result of high Calcium levels. For example: carbonate scale always forms in the hottest places first. It is not very common and to cure your pool of this you would need to bring your chlorine level up to very high levels, around 10-20 ppm. And we say "thankfully" because calcium phosphate is extremely hard to remove and clean off. This reaction, however, may be misleading because it does not account for how chlorine gas dissolves into the water. Question: Do you know why a saltwater pool would cause skin and eye irritation and coughing in several different people? Answer: First of all, your filter could be clogged and needs a backwash. As such, to lower free chlorine level, reduce the percentage setting in your chlorine generator. We have seen a pool with over 40 ppm (40,000 ppb) before...once. My children take swimming lessons at an indoor saltwater pool. Scale really forms most immediately after the pump shuts off, and water stops flowing through the cell. Yes, it's safe to safe to swim since 25k ppm salinity level is still within the recommended range and on the lowest side, unless it reads above 35,000 ppm. Chances are if you have a salt water pool you have seen some type of white flake blowback at one point or another into your pool or spa. If you have Free Chlorine Level (FCL) problem in you pool, whether it's high or low, save your time by visiting how to correct FCL in a saltwater swimming pool and learn in details how to regulate (reduce or increase FCL) the level of chlorine produced by your Saltwater Chlorine Generator (SWCG). SC-1000 can help, but in the short term, you might be better off vacuuming the flakes and removing them from the pool. Question: My Saltwater Chlorine Generator indicated low salt. I am a new pool owner with a SWCG. Will we be able to run the system - I know it will reduce chlorinator's cell life? You can do this while the pool's full. Recently, my daughter has gotten ill (vomiting) a few hours after coming home from the pool - her most recent two visits. Answer: Calcium levels are high, to reduce its level, drain and refill a portion of your pool water, maybe halfway. High pH levels in a saltwater pool leads to formation of calcium buildups and you need to measure your pH regularly to avoid white flakes or calcium scaling. Copper can get into your pool if you use a Well fill water or tap water with copper for your pool, or using hair products with copper. I just opened my pool and added the recommended salt and it turned cloudy and my sand filter has been running and is still cloudy do I need to check chemical balances or should I shock it sand filter hasn’t been running for 24 hours yet before I start up the salt system, how to correct FCL in a saltwater swimming pool, Hayward's AQR15 AquaRite Salt Chlorinator. The average lifespan of a salt cell is 3-5 years in most SWCGs, after which you need to replace the old cell with a new one that will produce sufficient chlorine. Also, foam may be forming because of low calcium levels. If you really had calcium phosphate scale on your salt cell, it would be time to buy a new salt cell. All will be fine. Barack James (author) from Green City in the Sun on July 20, 2019: Turning down the nano CG is enough and should work in stabilizing your chlorine without having to shut it. Also, make sure the salinity level is between 2500 and 3500ppm so that the right amount of chlorine is produced. Instead, it's usually more like 50-80% of the time. Here are the things you should know about maintaining a salt water system. It's the perfect storm of high-LSI factors to cause calcium to fall out of solution. Before adding chlorine, get your Cyanuric acid level in water. Run the filter continuously overnight. You need a test kit that can measure high FC levels like LaMotte ColorQ Pro series or Taylor Technologies test kit 2006 with FAS DPD. Repeat until no stain is seen. We have 2 yr old, outdoor, pebblecrete pool holding 20000 litres. Cal hypo comes with high pH and calcium and you are likely to fight high pH and calcium scaling if you use them. Use muriatic acid or hydrochloric acid to lower TA. Answer: Check and ensure that the level of salinity in your pool is between 2500 - 3500 ppm for chlorine to be sufficient in your water. 1  Titanium is used because it is less susceptible to corrosion. And while this can help prevent scale, nothing is ever 100% with pool chemistry. When scooped out and dried, the flakes … After the white flakes are blown into the pool through the returns, they can get dirty, they can tumble around, and they can begin to look more translucent. This article is accurate and true to the best of the author’s knowledge. There are plenty of reasons to remove phosphates, but scale in a salt system is not high on that list. Question: Besides draining the pool what can be used to reduce high levels of cyanuric acid? Finally, check with your filter cartridges if they need backwashing or replacement because poor circulation will cause lots of chloramine in your water. ... vacuum the pool's lining using a suction or pressure vacuum. Another cause might be very high FC levels but this is unlikely because it can only be true in FCL of 10ppm and above. Soon, it may develop low chlorine problem is salt cell is not working efficiently. You need to ensure that all chemicals are balanced all the time to avoid cloudy water and growth of algae. Answer: If you have high free chlorine level in your saltwater pool means the percentage setting in chlorine generator is too high, the higher you set the percentage setting in your chlorine generator the higher the production level of chlorine. What is the fix? As you know, we are a manufacturer of a phosphate remover. The levels of TDS increases as chemicals are added and as organic matter dissolves in the water. Then, test that area of the water to get a preliminary salt reading. We recommend a strategy of lower alkalinity and higher calcium to allow you to have a higher pH without forming scale. Basically, all chlorine generators are have a percentage setting that controls how much chlorine they produce and how much time the pump runs to produce enough chlorine. Question: The filtration system is not circulating water in our pool. The correct value of cyanuric may also differ with geographic locations, depending on temperature and how much sunlight is available during the day. Pool looks great. Working without any chlorine stabilizer in a saltwater pool will overwork your salt generator since it will be working at a high percentage and pressure to keep correct levels of free chlorine in your pool water. Unfortunately, not all of the … Using a metal like iron, for example, would require much higher salt levels in order to produce chlorine. 28,440 ppb phosphates is really high and unlikely, but it is possible. Question: My grandchild pooped bubbles in our pool. As we know from studying the saturation index (LSI), LSI violations are localized events. Another, more common-sense reason for suds in the water is due to cleaning products: pool owners who are cleaning the tiles near the water line of an in-ground pool, or the vinyl liner of an above-ground pool… Let's get into it. Any ideas? As water circulates at, say, 50-80 gallons-per-minute (on a residential pool), minimal (if any) scale should form in a salt cell if the LSI of the pool is balanced slightly below 0.00 ( yellow  on the Orenda App). Barack James (author) from Green City in the Sun on July 30, 2020: Use Sodium Bicarbonate only to raise Total Alkalinity and Sodium Chloride to raise salinity level in your Saltwater pool. One side is positively charged (anode) and the other is negatively charged (cathode).1 See the diagram below: The electrolysis reaction in a salt chlorine generator looks like this:2, 2NaCl + 2H2O → Cl2 (gas) + 2NaOH + H2 (gas) salt + water → with electricity⚡️yields→ chlorine gas + sodium hydroxide + hydrogen gas. This could be the issue with your chlorine level. So we looked into it.3  We have so far concluded that while calcium phosphate might be possible in salt systems, thankfully, it is rarely the case. i have white flakes coming from the inlets. Your pool should be at a pH between 7.4 and 7.6. Before adding chlorine ensure that it is less than 3ppm. If you have calcium carbonate in your pool water, it forms white flaky scales. If possible, always avoid stabilizers unless you have an outdoor pool in a hot and humid climate. Question: Salt water with fiberglass - how do we permanently remove brown staining? Question: My Ph, alk, free chlorine, stabilizer, salt, calcium hardness, etc in salt water pool is correct but water is cloudy. The second issue is Calcium buildup on the salt cell, make sure that your salt cell has no calcium building completely because this will impede the functioning of your cell in producing enough chlorine. Question: I need advice on alternatives for cyanuric acid, which is not available here in Burma. Question: I have a few small rust spots in my fiberglass small saltwater pool. The recommended free chlorine levels should be between 2-5 ppm all the time, depending on the level of cyanuric acid in the pool as indicated in this chlorine/CYA chart. If free chlorine is still reading low after doing all the above, you might need to add a small amount of liquid chlorine to boost the levels. It stopped randomly and red light on aqua rite illuminated on "no flow" last night performed our first backwash and rinse cycle and was well. Related 'From the Experts' Article: How to Avoid Salt Pool Maintenance Issues. 3  Lei, Song, Weijden, et. You need to closely monitor the cell to ensure that there is no calcium buildup, which causes a low production of chlorine. As such, you need to add chlorine shock manually to raise the level. Most saltwater systems are produced with a button or switch to allow you to “super chlorinate” water in the pool… Barack James (author) from Green City in the Sun on March 28, 2019: Hollo Larry, vomiting in kids after swimming is majorly caused by swallowing pool water that may cause recreational water illness and chlorine poisoning and all these may lead to digestive distress, such as abdominal cramping, vominting, and diarrhea. Higher levels of calcium hardness, a higher pH and a higher temperature can all reduce the needed level of phosphate. Often times we hear of residential salt systems being run wide open (100% output) all the time. 4  Lenntech Technical Manual. Turning off the chlorinator, additional swimtime by multiple people, as much direct sunlight as possible, and heating the pool don't seem to make a dent in reducing the high level. I'm looking for expert help. Could it be the pump or filtration causing the issue? Dispose of the acid solution and rinse the cell with a garden hose. The most common cause of foamy pool water is a drop in calcium hardness levels in your pool. SWCG maintenance is all about cell cleaning and replacement, period: Chlorine production happens in the salt cell, and a defective cell will lead to less or no production of chlorine. Drain some of the water from your pool using a hose or pump. The harder you hit the algae in your first shock the better. The only solution is to prevent them from drinking pool water. Make sure your calcium hardness is between 200 and 400ppm and run your pump and foam should clear up. If it's saltwater pool this could be caused by high salinity level or excess Calcium Hardness Increaser. The best thing you can do if you can't wait for it to reduce by itself is to drain and refill a portion of your pool water. After 24 hours, add a filter cleaner to your pool. We have vaccumed and backwashed multiple times in the last month or so and we just had a new salt cell put on. Most salt chlorinator users, including myself, use zinc anode as part of the pool system to form stainless metal parts. The ideal range of cya is between 70 to 80ppm, but to avoid using a lot of chlorine, the idea level is 70ppm. If you own or maintain a saltwater pool, there's a good chance you have seen calcium flakes in it too. Convert an Above‐Ground Pool to Saltwater. Ideally, the recommended levels for pH should be between 7.2 and 7.6, with the most ideal or optimal level of 7.4. Brush pool walls and bottom thoroughly. In some cases, you will be forced to increase the pump run time to allow for the production of sufficient chlorine when free chlorine is too low. Question: Our pool became cloudy. -Raise FC sodium hydrochlorite liquid chlorine to 2ppm and watch if more stains occur. The ruthenium coating is used to maximize the production of chlroine gas from chloride ion. This strategy is probably the most important way to prevent scale flakes, and there are several ways you can do it using the Orenda App calculator. But if it's operating at 75%, it's only operating 9 hours a day (0.75 x 12 hours = 9 hours). Barack James (author) from Green City in the Sun on July 23, 2020: Clorox Pool Salt is one of the best out there just to assure you that it's not causing bleach smell and bleaching out your garments. Yes, saltwater pools are chlorine pools. The good news is that pool foam is not too difficult to combat, but it can be pretty time consuming. It is recommended that all information from this or any other source is to be performed assuming individuals performing these functions will consult local state and federal requirements before you act upon it in any way. Indeed, high phosphates do contribute to added chlorine demand, which is perhaps what people notice...but the phosphates themselves do not have anything to do with salt. So let's hone in on how chlorine dissolves into water: Cl2(gas) + H2O → HOCl + H+ + Cl-Chlorine gas in water yields Hypochlorous Acid + Hydrogen and Chloride. Also, this may result in more dissolved substances in the water and that may be very costly to correct. Pour the solution into the cell and leave to soak for 5 to 10 minutes. Another parent told me that her child was similarly ill, recently. But it is not in this case. How to get rid of pool foam in 5 steps. The good news is that, with a good pool maintenance routine, you can keep your water balanced and keep pool calcium in check (and you can kiss the flakes, stains, and leaks goodbye). You need to reduce calcium level by draining and refilling a portion of your pool water. Test for copper metal using reliable test kit like Lamotte ColorQ Pro 11 and take the steps necessary to prevent any more copper getting in the water by following instructions in this article: https://dengarden.com/swimming-pools/Why-Swimming-... Salt water pool filter cartridge and plastic parts of skimmers turning blue. I added salt and brought the salt number within the specs. Most saltwater pools do not run the salt chlorine generator 24/7. And in pools with attached spas, flakes are often found in the spa more than the pool because of how the plumbing is designed. Just like a chlorine-based pool, saltwater pools turn cloudy when chemicals are not balanced. If it's a saltwater pool, they very likely came from the electrolytic chlorine generator (ECG). The only way to correct high calcium hardness is to drain part of your pool water and then adding fresh water. Those white flakes are the scale that has just sloughed off a titanium ECG plate as the unit reversed polarity. When you vacuum them up, they may not look as crisp as when they first show up in the pool, but we believe they are the same flakes after being in the pool for several days. From my own experience with a saltwater pool for more than five years now, the major problems you will encounter in a saltwater pool are calcium buildups that come in your pool as white flakes, low chlorine levels that cause cloudiness, low salinity, salt chlorinator maintenance, and corrosion issues. Electrochemical Induced Calcium Phosphate Precipitation: Importance of Local pH. For example, if it was caused by algaecide or cheap chemicals, it will usually break down on it’s own if you just give it a few … What should I do? For one, saltwater pools, thanks to the salt added to the water, have a baseline TDS of at least 3000 ppm more than other types of pools. To accurately test and adjust important chemicals such as pH, free chlorine, combined chlorine, total chlorine, total alkalinity, cyanuric acid, and bromine, I use LaMotte ColorQ Pro 11 digital pool water test kit that takes a very accurate measurement for all the chemicals at once. So you would be producing chlorine 7.5 minutes out of every 10 minutes, with 2.5 minutes off. Also make sure your salinity level is within the range because excess may result in high production of FC especially when above 75%. I have just had a salt … Use a cup or a bowl to take a 4 – 8 ounce water sample with the flakes floating it in. The sun could be also bleaching out your clothes and this depends so much on the colour of the clothes used. The average temperature outside: 90 degrees. No, we have not tested all of them, but have tested some, and with our knowledge of the LSI, calcium carbonate makes the most sense. LSI balance is critical here. Just know that it is by far the most common form of scale, and it is what every white flake in saltwater pools is made of...at least in our experience. How can I safely remove them? The only issue I have is a bleach like smell and a bleaching out of some article of clothing. So when we teach classes, we often ask the question of where scale forms first. The higher your pumps runtime the more chlorine will be produced in the Chlorine Generator and the higher your free chlorine level will be in your water. Answer: Chlorine depletes by itself and there is no need to add neutralizing chemicals which might cause more chemical problems in your pool. We of course need to get rid of the cause of the flakes too, which means you will need to clean the salt cell following the salt system manufacturer's instructions. We recommend you consult a local pool professional before acting. Question: How do I increase the stabilizer level in a salt water pool? Dead algae turns gray as it dies and must be removed from the water through filtration. Alternatively, you can use head gears when swimming to protect your hair from getting the green tint. Refill with fresh water and test for salinity, repeat the process once or twice till you get your salinity within the range and balance your chemicals starting with pH and TA, then FC and Cyanuric acid then all other chemicals in your water. As long as you consistently maintain your hot tub with a simple and quick cleaning routine, you shouldn’t run into these … This can be reversed by reducing total dissolved materials in your pool. Are these levels too high? Barack James (author) from Green City in the Sun on May 06, 2020: The ideal range of salinity level for a saltwater pool is between 2500 and 3500 ppm. Almost everyone says something like "tile line" or "in the spa" or "the spillway". Answer: Your salt cell might be dirty and may need cleaning to work efficiently. This type of hard white formation may indicate that a section of the pool surface has de-laminated (pushed out) from the main pool structure. Pools have literally had to cut open their filters and use jackhammers to get the sand out because of calcium phosphate formation in the filters. Answer: High pH may be caused with Calcium Hypochlorite(granular/powder chlorine) pool shock if used regularly to shock swimming pool. This dramatically reduces the chances of scale formation by rapidly lowering the LSI back to normal range (assuming your pool is LSI-balanced, of course). Related: LSI Balance and Calcium Management (Pillar 1). You can chemically dissolve them with the right pool chemistry, but this takes time and might not be entirely practical. To get rid of cloudiness, you will have to do a liquid chlorine shock to raise the level of free chlorine (since the chlorine produced by the generator is not enough; a chlorine generator just assists you in maintaining the level of free chlorine). Raise your pH using any pH plus or 20 Mule Team Borax, and TA using alkalinity increaser. Having a trouble-free saltwater swimming pool is not a rocket science; it’s all about monitoring (testing) chemicals used in the pool regularly (at least weekly) and maintenance of chlorine by regulating chlorine generator. When the salt cell reverses polarity, the carbonate scale fractures and loosens, and flakes of calcium carbonate are carried by the circulating water out into the pool. Answer: Backwashing should fix the problem, if it does not work there could be a problem with your filter and it may need replacement. Maintaining a saltwater pool isn’t quite like maintaining a regular chlorine pool. To avoid escalating Cyanuric acid levels in your pool, avoid using stabilized chlorine-like dichlor and tablet chlorine to sanitize your pool, but use liquid chlorine(Sodium Hypochlorite). Try cleaning the salt cell and observe any change in the salinity reading. Vomiting is normal for toddlers in many cases during swimming because they drink a lot of pool water. Scale also causes pool finishes to feel rough and appear discolored. But the truth is, on saltwater pools, the first place to form scale is usually in the salt cell. They are still calcium carbonate. When adding water with a garden hose, allow it to run for a couple of minutes prior to placing the hose into your swimming pool. Answer: Skin and eye irritation is commonly caused by low pH and TA levels. So if your circulation pump is running for 12 hours a day, and your salt system is operating at 100%, it is producing chlorine 12 hours a day. You can try using light coloured clothes for swimming as opposed to heavy coloured ones that bleach out easy when exposed to the Sun or more of chlorine. Barack James (author) from Green City in the Sun on April 02, 2019: Cloudiness in any pool be it salt water or chlorine based pool is associated with low chlorine level. Question: Why would my cell indicate 100 ppm when I added 3 bags of salt? Taliyajking@gmail.com. Answer: You may need to clean your salt cell if you have not done so in a while. Remember to be very careful when using tablet chlorine since you can't lower the cyanuric acid level unless you drain and refill part of your swimming pool water. Question: I have a continuous very high free chlorine level. Answer: Add calcium chloride carefully not to exceed the recommended level. Pool Service Prices Will Increase in 2021. All information provided is intended for educational purposes and is not implied to replace consultation with a qualified pool professional. Expanding on the relationship of phosphates and saltwater pools, salt and phosphates do not bind together. If you lose less than 1ppm free chlorine, that is copper stain and you need to add metal sequestrant in your water. Those two factors are the high pH of sodium hydroxide, and to a lesser extent, heat. Maintaining free chlorine levels between 1 and 3 parts per million (ppm) will prevent the growth of algae. Answer: If you are sure that all Chemicals are well balanced including Salinity and Calcium Hardness, you might be having particles and you may use pool flocculant and then vacuum the pool. Scale Problems In Saltwater Pools. Keep in mind that salt levels will be recycled during the process of chlorine production, and you may not need to add more unless the level falls way below the recommended range. Vacuum to waste, if possible, to drain the water directly and avoid having the mold pass through your filter. Will this tear up our saltwater system? However, if they vomit lots of food, that may be food poisoning and you need to seek medical help. Question: Why is my saltwater pool's pH level always high even if I add pH reducer? Ever. If the flakes disappear, they are most likely a … Part of the problem with salt cells forming so much scale was described earlier in this article. So, fix salinity first by draining and refilling pool water, then fix the pH by adding pH plus, then finally do some cleaning on your salt cell if you've not done so in a while and your chlorine production should just come back to recommended level. Answer: Currently, it's very unfortunate that there is no chemical to lower Cyanuric acid levels in your pool or spa apart from draining and refilling or at least refilling your pool with fresh water. What could be wrong? We could expand this even further and show how hydroxide and Chloride react, but it's just getting more complicated than we need to be. The pool seems to be "eating" the salt. If sure your free chlorine level has been balanced and algae breakout is not possible, you may have copper metal in your pool and is being oxidized by Chlorine to produce green solution. The white flakes in salt pools are calcium carbonate, with very few exceptions. I tested the water for salt content, and sure enough, it was low. There are two types of calcium compounds that form in pool water and create scaling--calcium carbonate and calcium silicate. If the salinity and everything mentioned above is just fine, but free chlorine is too low, this may be the result of heavy pool usage and you may need to add small amount of regular chlorine (or adjust your chlorine generator to produce more chlorine). 2) White calcium icicles (nodules) Most commonly, there are approx. Here's Why. This is helpful.The levels were way off when we checked with Clorox strips and we've tried everything to balance them out and nothing is working. There are three possibilities of what the white flakes are. In fact, if you try to maintain it the same way, you could end up damaging your pool and its support systems. Yes, you need to drain the pool because no chemical can do that. Pool not exposed to direct sunlight. Free chlorine should be 3ppm, which should also be the value of total chlorine and that means your combined chlorine is always 0ppm for a well maintained swimming pool. The process–and its byproducts–explain why the calcium flakes occur. Is it safe to swim? SC-1000 can help, but in the short term, you might be better off vacuuming the flakes and removing them from the pool. Located in NSW (Australia). On the other hand, high TA will cause cloudy or murky pool water since the pH will also scale high as the Alkalinity rises, affecting free chlorine performance. For spa Calcium Hardness(CH) should be between 100 to 150ppm, start by measuring and balancing your calcium levels. This will not prevent all salt system maintenance issues, but it should help you reduce the frequency of cleaning. Alternative for cyanuric acid? Ever find little white flakes on the bottom of the pool near the return? Ideally, even if there is no buildup, it is recommended to clean your cell at least every 6 to 12 months. Since chlorine is the primary reason for creating this reaction in the first place, let's designate chlorine as the main product of the reaction, and sodium hydroxide and hydrogen as byproducts. If it drifts to the higher side, TDS significantly affects free chlorine levels and other chemicals and may cause cloudiness in the water. Very low salinity levels may bring down your available free chlorine to 0 ppm, which will almost certainly encourage algae to thrive. The pool company has not returned our call. Answer: Your chlorine is too high. That is, unless you like using a hammer and chisel. We found several sources (which we will not link here out of respect) that make the case that calcium flakes are calcium phosphate, and therefore you need to buy a phosphate remover. Pool guy says all the chemical level are correct, but the problem has been going on for over a month! The second cause might be a lot of accumulated urine in your pool water. They generate chlorine on site. Saltwater can conduct electricity better than fresh water. It was clear when we removes the cover to raise water levels, however after our pool guy came over to officially "open" the pool and add the proper chemicals (along with salt for the 1st time since we got the pool only 6 months ago), its now super cloudy. Any ideas? Next morning, turn the filter off, brush pool thoroughly, and allow material to settle and vacuum. Add Filter Cleaner. Think about it: the salt cell is still hot, high-pH sodium hydroxide is still in the area, and the water just stopped moving. Either way, you’ll want to get rid of them. Just like eliminating chloramine and algae, you need to shut down your SWCG and shock your saltwater pool manually using harsh chlorine in order to get rid of ammonia in your swimming pool. Is this going to damage the equipment? In most cases, balancing pH and TA in both saltwater and chlorine-based pool is tricky and the only way is by first reducing both chemicals using muriatic acid and then raising pH through aeration to get the correct balance.
