I know it's mostly "play around with it until it's good", but I like to have a "refined" target, if you will, for things.
So, doing some reading, I think to get to 3.0 ppm of free chlorine I think I would need .4 lbs of chlorine. This is based on 16000*8.34 (lbs/gallon of water) = 133,440 pounds water and if I multiply that by .000003 (3 ppm), I get .4, or 6.4 ounces.
Does that all sound right or am I way off?
Because, if that's the case, my SWG tells me how much chlorine it's supposed to produce and I have my target. The IC40 says running full tilt it will produce 1.4 lbs of chlorine in 24 hours. So, if I ran my pump for 7 hours at 100%, that would give me my target.
Do those numbers sound rational?
