The DuoClear salt system utilizes Zodiac Nature2 and Clearwater technologies, combining salt and minerals for powerful sanitization. This system delivers minerals, low levels of chlorine and a trace of ozone for pure, gentle pool water with no harsh chemical smell or irritation.
This system is for in-ground pools up to 35,000 gallons. The Nature2 cartridge is not included and is sold separately.
Control Panel Functions:
Please note: The DuoClear system can be used with most types of pool chemical treatments except bromine and bromide based chemicals, biguanide products, and copper based algaecides.

What size salt system do I need for a 18x36 in ground pool?
An average rectangular 18x36 (4.5' average depth), would be about 22,000 gallons. The W379310 would be double your capacity but over-sizing the unit would be a benefit because it puts less stress on the salt cell. You can either go with the W379310 or the smaller W379110. For the price difference, I would recommend the larger unit.
Will the Zodiac DuoClear W379210 eliminate chlorine?
The Zodiac DuoClear will not eliminate chlorine because it is a salt chlorine generator. It does eliminate the need to add shock or chlorine tablets. The DuoClear combines a salt chlorine generator with a Nature2 mineral cartridge. The mineral cartridge allows the pool to operate at a much lower chlorine level.
