The saltwater chlorinator uses a salt cell that cleans and sanitizes the water through electrolysis. The salt gives the water conductive properties so that when it passes through the electric plates held with the salt cell it causes electrolysis. This results in a chemical reaction and makes chlorine from the salt.
By adding a small amount of granulated salt, common chlorine will be formed. This does not stay as chlorine as during the process it is made back into salt. In this way, the salt does not have to be replenished until six months after it has been installed. The chlorine being a naturally made substance along with the salt will also reduce any stinging to the eyes that is caused by the chemical and poses to no health hazard to children or others using the pool. -
Ozone is a great oxidizer of water more so than even chlorine. The only substance that is stronger is fluorine, but that is another chemical to avoid in a swimming pool. Ozone is good for many different components of keeping a swimming pool clean, not just killing bacteria.
This chemical-free substance kills viruses, fungi and parasites aside from bacteria. It also removes calcium carbonate residue and scaling and prevents more from being deposited. Ozone doesn't change the pH of the water, nor does water affect that of the ozone. There are many models available with varying prices depending on the size of the pool and other factors. -
Ionization is the cheapest of all methods for sanitizing pool water and was developed by NASA. It can save families up to 80 percent of pool maintenance costs. It produces pure, clean water with the least amount of monitoring possible. There are kits that you can set up yourself, or you can have someone else install it.
Ionizers replace any need for the chlorine by replacing it with copper ions. It gives a new feel to the water. This ionization process kills all of the bacteria, fungi, algae and waterborne pathogens while keeping the water crystal clear.
