There are several types of sanitizers available for your swimming pool. Our pools come with a Rainbow in-line chlorine dispenser that uses chlorine tablets to sanitize the water. Many of our customers choose to use the IntelliChlor electrolysis system that converts salt to chlorine. This system will save you time and money. Ozone is another good way to sanitize. It can be used with the chlorine tab or salt system. It will oxidize the water whenever the circulation pump is running. It is the strongest oxidizer available for residential swimming pools and will reduce the need to “shock” your pool.

We use the Mineralizer ionization system and it can reduce the need for chlorine in your pool. Pentair's IntelliChem system will monitor your chlorine and pH levels and adjust them automatically. This system intergrates with their IntelliChlor and automation systems.
