Hello,
back in the summer i had an issue with extremely high CYA which caused something to grow; i finally got by CYA down by draining/filling pool.
i then did the "SLAM" and was able to maintain chlorine levels with other readings WNL. I now strictly use household bleach 8.25% to maintain chlorine levels based on my CYA levels. Now that issue is under control i was wondering about my ph levels.
it seems to be the only thing out of "normal" range. it's been about a week since i tested my water last (since it's winter i do it weekly) and we received about 4-5 inches of rain which i understand can help reduce TA. Prior to the rain, TA was around 120, ph was 7.8, CYA 50, and CL 4 (these were pool store readings).
here are my test results using TF-100 test kit:
ph 8.0 (i initially used the "quick" test kit but i find it difficult to read - seemed to be somewhere between 7.8 and 8.2 so i used a ph test meter after calibrating it and got 8.0)
Chlorine - 3
FC - 0
Calcium hardness - 300
TA - 100
CYA - 50
i've read about a process to reduce TA which will help the ph but i didn't know if i needed to go to that extreme yet since my TA seems to be in the normal range for my chlorinated fiberglass pool or just "wait and see".
thanks for your help!
