How To Clean Your Hayward Salt Chlorinator Turbo Cell

Did you know it’s always a great idea to inspect your Hayward TurboCell for calcium build up before it’s put into operation? Leaving calcium deposits on the internal TurboCell plates can actually lessen your TurboCell’s effectiveness at producing chlorine and can ultimately shorten its lifespan. For optimum TurboCell operation and longer life, you should inspect your TurboCell approximately every 3 months of operation, or 500 hours, and clean the cell if necessary. TurboCell cleaning frequency will be dependent on several factors such as pH, calcium hardness levels of your pool water and hours of operation. The pH and calcium hardness levels are the two factors that have the greatest impact on how often your TurboCell will require cleaning. Calcium buildup (or scale), is one of the most common and serious challenges in salt chlorinated pool maintenance, partly because it typically forms first on the salt cell plates where it can remain undetected until the problem advances.  Once scale forms, it lessens the effectiveness and life span of the salt cell, which can lead to premature cell replacement. Our Hayward Aqua Rite salt chlorination system, the world’s #1 salt chlorinator, has a built in reminder to inspect and clean the cell every 500 hrs. This salt chlorinator is the convenient alternative to conventional chlorine, bringing your pool the very best in soft, silky water with no more red eyes, itchy skin, or harsh odors. How to Clean Your Hayward Salt Chlorinator Turbo Cell: Turn off the power to the system and deactivate the pool pump before removing the Turbo Cell. Remove the Turbo Cell.  Once removed, look through the cell and inspect for scale formation (light colored crusty or flaky deposits) on the plates and for debris that is caught on the plates.  If no deposits are visible, reinstall the cell. If deposits are seen, use a high pressure garden hose to flush the scale off. If a high pressure hose does not remove the majority of deposits, then use a mild acid wash. Be sure to wear rubber gloves and appropriate eye protection.  In a clean plastic container, mix a 4:1 solution of water to muriatic acid (one gallon of water to one quart of acid). Caution:  ALWAYS ADD ACID TO WATER – NEVER ADD WATER TO ACID. Fasten the Turbo Cell to Cell Cleaning Stand with the cord side down.  Before filling Turbo Cell with muriatic acid solution, place a container underneath to avoid any spills.  Fill the Turbo Cell to the top with the solution and let soak for 15 minutes. Empty the Turbo Cell and inspect.  If clean, rinse with hose and reinstall.  If there are still deposits after soaking, repeat the soaking procedure until clean.  The water/muriatic acid mixture can be stored for later use or it can be disposed of.  Follow the chemical manufacturer’s recommendations when storing or disposing the water/acid solution. Reinstall the Turbo Cell.  Press the small diagnostic button next to the display for 3 seconds to stop the flashing Inspect Cell LED

Pool Water Chemistry 101

Pool and spa water chemistry along with proper filtration is the key to clean, healthy water. It doesn’t matter if you have 100 or 1,000,000 gallons of water, the same balance levels and chemical types are required—only the quantity will vary. Everything that enters the body of water affects water balance: swimmers, rain, pollution, animals and chemicals. Every pool, each season, creates its own demand for different chemicals. The pool in your neighbor’s yard, with the same system and environment may react totally different than yours. Every pool also develops a pattern each season. After observing how your pool reacts to different bather levels, rain and the environment, you will get a handle on your pools chemistry pattern and what’s required to keep the water balanced. Accepted levels for balanced pool or spa water: Pool Spa Total Alkalinity Plaster 80-120 ppm 80-120 ppm Vinyl 100-150 ppm 100-150 ppm PH 7.2-7.6 7.2-7.6 Bromine 2-4 ppm 3-5 ppm Chlorine Total 1.0-3.0 ppm 2.0-4.0 ppm Free 1.0-3.0 ppm 2.0-4.0 ppm Cyanuric Acid 30-100 ppm 30-100 ppm Calcium Hardness Plaster 200-400 ppm 200-400 ppm Vinyl 175-300 ppm 175-300 ppm TDS < 2000 ppm < 2000 ppm Copper < 0.3 ppm < 0.1 ppm Iron < 0.3 ppm < 0.1 ppm

The Science of Balanced Water

For people with water issues, understanding what’s happening and what to do about it can be difficult and treatment expensive.  The key is to stay on top of it by regularly testing and treating the water.  All too often, pool owners think that chlorine, either traditional powder, tablet or liquid treatment or by salt chlorination, is enough to cure all that ails the water.  It’s simply not true.  The water must be in balance or the chlorine that’s added can become ineffective. Perfect water balance is determined by pH, alkalinity, calcium hardness and Total Dissolved Solids (TDS).  For pool water to be “balanced”, all these factors must stay in their proper range. The ranges may vary slightly, depending on the finish of the pool and the average temperature of pool water during the swimming season. pH is the most important factor in balancing water. It’s measured on a scale from 0 to 14, with 0 being the most acidic, 7 being neutral and 14 being alkaline. pH must be maintained in a narrow window between 7.2 and 7.8 for a pool to be considered balanced. Pure water is neutral. It’s only when things are dissolved in it that it skews one way or the other. This is a crucial point – high pH lessen the effectiveness of the chlorine that sanitizes a pool. If your pH is out of whack, it may not matter how much chlorine you dump into the water.  When pH drifts up, water becomes alkaline and creates an environment where mineral deposits (scale) can form and chlorine becomes ineffective at its primary task – killing bacteria and algae. The secret to controlling pH lies in controlling the alkalinity. It acts like a ceiling over your pH, so the pH can only rise so high. It’s important to control the alkalinity first because it makes balancing pH easier. Alkalinity needs to stay within 80 to 120 ppm. Calcium and total dissolved solids (TDS) such as magnesium, above 300 parts-per-million (ppm), make it hard to get clear water and it compromises the effectiveness of the chemicals. This can be commonplace, depending on your location. For example, hardness in Phoenix tap water has been seen as high as 1000ppm. Besides tile scale, other severe warning signs of high levels of hardness include scaling on pump, filter and plumbing lines, white deposits in filter sand, white stains on decks and landscape and increasing disinfectant chemical consumption. Unfortunately, high levels of minerals like calcium and magnesium cannot be cured through normal pool maintenance. These minerals need to be removed. Refilling your pool with the same water you started with is self-defeating, wastes time and water. Some professionals recommend adding a compound that binds to these minerals, but that’s a short-term solution. Cloudy water can reappear. If you’re in a high mineral area, the best way to control an out-of-control calcium or magnesium situation is to have water trucked in.

What is ORP?

ORP (Oxidation reduction potential) measures the oxidizing capacity in water.  It is a proven measurement mandated for commercial pool sanitization now available for residential pools.  Unlike most home test processes, ORP is not fooled by the effects of pH, TDS (Total dissolved solids) and other factors.  Most home test kits and strips only report free chlorine and other less effective chlorines.  Only ORP can deliver further detailed analysis of the more important free Chlorine.  It differentiates free Chlorine’s components HOCL (Hypochlorous acid) and OCI- (Hypochlorite ion).  OCI- is a slow-acting sanitizer and HOCL is up to 300 times more effective.  ORP targets HOCL, a more fine tuned measurement of the effectiveness of Chlorine and water quality. Exhaustive global studies have reported on the relationship between ORP and chlorine’s activity with germs and bacteria concluding that ORP is the only significant predictor of water bacterial quality.  Subsequently, in most states, the highly regulated commercial pool industry requires ORP testing. Simple Translation: ORP is a measure of the cleanliness of the water and its ability to break down contaminants. ORP sensors measure the dissolved oxygen. More contaminants in the water result in less dissolved oxygen and lower the ORP level. Not good! The higher the ORP level, the better the water can destroy contaminants. Great!
