Will the Zodiac DuoClear W379210 eliminate chlorine?

A  Answered on 9/28/2012 by InyoPools Product Specialist Patrick P.

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.

What size salt system do I need for a 18x36 in ground pool?

A  Answered on 1/21/2013 by InyoPools Product Specialist Patrick P.

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.
