    Salt Water Chlorine Generators

    Hi All,

    I'm doing research on SWCG's for spas. I've been looking at three portable ones, Spa Pilot, ColorChlor and Nexa Spa. The first two have an output rating of ~15 grams chlorine per day. The last one has a rating of ~100 grams per day. All at 3000 ppm salinity. The last one claims it can produce enough chlorine to sanitize a hot tub (~50 grams/day) at 1500 ppm salinity.

    My question is, how much Free Chlorine (FC) will they produce in a 350 gallon tub?

    Anyone know what a Gram of Chlorine is in terms of FC ppm in a 350 gal tub?

    15 grams of chlorine in 350 gallons is about 11 ppm.
