According to Hayward my SWG can produce a maximum of 1.4 lbs of chlorine/day. So I did the math.....I think is correct.

1.4 lbs =22.4 oz a day(24 hours)

That's 0.933 oz per hour.

I run my pump at the moment for 10 hours a day at 1200 RPM (100 watts of power) turn over rate approx 3 times......yes I know that's probably over kill, but anyway. My output is set at 50%. Which means that the system will generate chlorine for 5 of the 10 hours.

That comes to 5 x 0.933 = 4.66 oz of chlorine. I f I plug that number into pool math I get 5 PPM of FC during my run time. My system seems to be maintaining ok. This gives me nice bench mark.

FC at 430PM hottest part of day =4.5ppm

TA = 125

PH = 7.4

CYA = 55 in progress of raising to 70

Salt = 3500

Water temp = 90F

CH = 250
