After resolving the issues from my previous thread, http://www.troublefreepool.com/threads/83657-New-pool-owner-weird-readings?highlight=weird+readings, my pool has done amazingly well! I ended up adding about 2 lbs of stabilizer, contents read 100% CYA. Resulting CYA level was 50 by TFPK-50 kit. Rechecked today, just because I had not tested in a while, after adding bleach last night. Readings: FC 4, TA 140, CH 175, CYA 0, PH 7.5. This seems odd to me as I thought you could only lose CYA by draining the pool? Have lost some water to evaporation, of course, but have not drained any water from pool. Would think refilling/topping off pool would not change amount of CYA present since none was drained out? I have another pound or so I could add, but wanted to see if this sounded right to you guys before I added more.
Thanks so much for all your help!
