Good morning, as the title says we just decided to turn off the 3" puck chlorinator and fire the pool service. We are about 2 months in with water in the pool and my CYA is @ about 65. Luckily we are getting rain all this week so I have already had to drain and 4 or 5 inches worth of water this week. We started the process of just using liquid chlorine in the last few days and I realize there will be a learning curve. I see people using smaller doses or Chlorine to raise the FC level in their pool. It seems that it is taking more for me to get the FC up where it needs to be. Sunday I added 60 oz and it only brought me up about 1ppm. So Last night I was @ 4.5 FC then I added 90 oz. and it brought it to 7 where it should be. Does this have to do with something in the pucks we have been using? or if we had a bunch of people in the pool sunday? I think once we get the FC up to where it needs to be it should be easier to maintain it there. It just seems I am using more than most. The calculator says to get from 4.5 to 7 I need 58oz of 10% liquid. Here are my numbers from last night after 90. oz of 10% bleach. The bleach from Leslies was inside and the production numbers were recent so I dont think it was old.
PH 7.4-7.5 (was too close to call)
