POOL WATER RECYCLING: Available in limited areas with hard water and drought restrictions, there are companies who bring a truck mounted reverse osmosis filter system to your house, and pump the pool water through a series of filters and treatments, to deliver perfectly balanced pool water back to your pool in just an hour or two. It’s not a cheap option, often costing $2 gallons, but sure is fast and easy way to refill the pool with softer water. You may not want to fill continuously, but most systems can handle 8-12 hrs per day of filling the pool.ĭELIVERED POOL WATER: In areas where pools and water wells are common, there are companies who deliver pool water taken from nearby municipal water supplies (fire hydrants), after treatment and softening. You can connect a hose to fill the pool with filtered, softened water by connecting a hose after the sediment tank or in the kitchen or laundry room. But most outside hose bib spigots aren’t connected to the water softener system. HOME WATER SOFTENER: Many homes that draw their water from wells are equipped with a water softening system, limestone filters that exchange calcium ions for sodium ions. If your tap water or treated and softened house water is much lower in calcium than your pool water, and you are allowed to drain and refill in your area (no water restrictions), lowering by dilution can be the best method to reduce water hardness in swimming pools.

To more accurately determine your pool water’s propensity for scaling, which is the main concern with hard water pools, you can run a Langelier Saturation Index, using the Pentair LSI calculator.ĭILUTION: Lowering calcium hardness by dilution (draining and refilling with softer water) is often the easiest method, and for many it’s the only solution that is recommended. You can use Dichlor, Lithium, Non-Chlorine Shock or bleach as alternatives to Cal Hypo pool shock. Thirdly, for pools with high calcium hardness levels, you may want to discontinue use of calcium hypochlorite pool shock, which adds a small amount of calcium to the pool when used. Add an initial dose each spring, and maintenance dosages every week or two, for continuous protection from cloudy water, stains and scale. These chemicals bind up minerals and metals to keep them dissolved, to prevent staining and scaling, but they deplete rapidly. The second most important thing with a hard water pool is to make regular use of a good Stain & Scale chemical, aka sequestrants or chelators.

Hard water pools are less likely to become cloudy or produce scale when the pH level is kept around 7.2 and Alkalinity is below 100 ppm. The most important thing with hard water pools is to maintain low pH and low Alkalinity levels, especially as the water temperature increases each summer. There are many pools that operate in the 400-800 ppm range, with special care of pH and alkalinity, and use of a Stain & Scale chemical, to keep the water clear and prevent precipitation and scale formation on plaster, steel and tile surfaces.
