Made by Nature2, the purifier easily connects to the pool's existing plumbing and uses mineral cartridges that last up to six months, Marcano said. Although the purifier's technology isn't new, it's only recently come down in price and attracted consumer attention, he said. Also easing maintenance are automated chemical feeders, long used in commercial settings and now reaching consumer price levels. One product consumers may not know about prevents algae rather than kills it after the fact. The product is poured into the pool to remove phosphates, a food source for algae.
Every pool gets algae at least once a year.
You could drink it if you wanted. Water evaporates quickly in Arizona, leaving calcium deposits and chalkiness on pool tiles. Compounding this is the state's hard water. Arizona pools can't be drained during summer, however, because heat and dryness crack plaster. Until cooler weather allows draining, Marcano said Calcium Reducer, a product packaged within mesh, can be added to the skimmer to pull calcium out of the water.
