Here's what I've figured so far, what I need to do is figure what my daily loss of chlorine is (taking a measurement in the a.m. and taking one in the p.m. after the sun goes down). I'll be able to see what my loss is from the sun. I can then figure out and play with my unit %'s to see what will stabilize it at the level i need compared to the cya and pool math calculator.
It would be interesting to see if the amount of chlorine it generates matches the rated output at a given setting. Measure your FC at sunset, fire up the swcg, and check the FC in the AM
Who is/where is the manufacturer of the various swcg sytems that are sold by Circupool?
