I thought I was doing pretty good with the BBB method, but I feel like I'm dumping a lot of chlorine in my pool to keep my chlorine levels up. In the beginning, I had no CYA in my pool, but recently added 20lbs and waiting for CYA Regeant to arrive to retest. Right now I add about 2 of the big jugs of bleach (1.5 gallons) per night ($5 per night). If I decrease the amount of bleach i add, I seem to run into problems again. I'm wondering if spending and adding this much bleach is pretty normal for this size pool? I get full sun all day. My kids swim in it practically every day, my 18month old is in it too , plus we usually have heavy bather loads on the weekends. Just want to know if this is what I should be budgeting for? Thanks so much!
