Chlorine can be purchased in the form of three-inch tablets, one-inch tablets, sticks, grains or liquid in bottles. Products that are listed as sodium hypochlorite are liquid chlorines and those labeled calcium hypochlorite are solid chlorine forms. Three-inch tablets are the most common form of chlorine used by most pool owners and are also the most inexpensive. They dissolve slowly though, so most pool owners prefer one-inch tablets since they work best for above ground pools, small in ground pools and spas. If you plan on buying cheap chlorine tablets, binders in the product don’t allow the tablets to maintain their shape and instead cause them to crumble in two or more days. Granular chlorine works as an alternative, but inorganic chlorine needs to be dissolved in a bucket of water before you put in the pool. It has to be done almost every day and the same goes for chlorine with organic compounds.
Cyanuric acid can be used as a more stable alternative as well, since it can’t be easily broken down by the sun. Test the levels again after placing any chlorine in your pool, to make sure the acid levels aren’t too high or you risk the chlorine losing its sanitizing ability. Additional helpful maintenance products are automatic chemical feeders and floating chlorine feeders that balance and measure the amount of chemicals in your pool. Carelessly adding chlorine has its repercussions and risks involved with increasing a pool’s high chlorine content are the erosion of filter and pump equipment.
