Tap an item when you have it. Test first — then buy only the conditional products your results call for.
Only if your situation calls for it
Metal sequestrant / metal remover
Only if a water test confirms iron, copper, or manganese.
Water clarifier
Only when water stays hazy after chlorine and pH are in range and the filter is clean.
Salt
Only for salt pools, when a salt test reads below your generator's range.
Store chemicals in their original closed containers, in a cool, dry, ventilated place, out of children's reach — and keep acids away from chlorine products.
