Hi, all
New to TFP but was on Pool Solutions for a long time. I have a 25 yd, 2 lane, 3 1/2 to 5 ft depth pool and since I just re-opened this week I can't remember how many gallons that is. Opened about 6 days ago, used calcium for opening bec Ca level was low and pH was around 8.0. Yesterday with full test kit the TA was 100. I can't figure out why my pH has gone down to 6.8 today (it was 7.5 yesterday). Is it the calcium I used? ANy harm in the pH's being this low? Thanks for your thoughts! Eileen
