Chlorine is necessary in swimming pools to deal with the bacteria that builds up within the water and treatment plant. Bacteria is introduced via various sources, including the swimmers themselves, and will proliferate in the warm conditions found in the pool. Water evaporation causes the total dissolved solids (TDS) levels to increase to levels far and above those of the incoming water and much of the calcium content coats the surfaces of the pool and associated plant. Body yeast, which is essentially dead skin shed by pool users, adheres to the calcium on the sides of the pool, causing a very stubborn tide mark. This scale becomes both a source of nourishment and accommodation for bacteria which, left untreated, poses potential health problems to users of the pool.
Appropriate levels of biocide, e.g. chlorine, are continuously maintained so that the risks are removed; the acidity of the pool has to be maintained at a neutral level to ensure this is effective. Maintaining a neutral pH is complicated by the precipitation of the calcium and the changes to pH caused by the biocide. Constant monitoring of free chlorine levels and pH and subsequent adjustments to the chemistry should ensure that the pool remains safe and comfortable, i.e. no pathogens nor stinging of the eyes.
the Scalewatcher® Pool Saver
models neutralize the conditions that propagate these problems, nearly eliminating this costly routine. The calcium scale deposits within the pool environment are dissolved back into the water. The results of this lead to a reduction in chemical usage of over 35% and a pool that is literally easier on the eyes. The tiles and stainless fittings look like new again, the water sparkles regardless of pool loading and eye irritation is considerably reduced.
