Chlorine Demand

[Watermom]

bmgo, you didn't tell us the size of your pool. But, 2-3 qts per evening is approximately what I use when we really get into the swim season with lots of hot, sunny days. Go ahead and bump your cya up to 40-50 and see if that works better for you.

Thanks for input. I filled the pool last year (16x32) and put in ~21K gallons.
The more I read about CYA the more confused I get. Some dont like any and I have read about some States banning use in Public pools as it reduces the effectiveness of CL so much. I quess it is a necessary evil as opposed to runing Chlorine into the pool all day. A great thing about using liquid bleach is the ability to manage FC more precisely.
Thanks again
