I have a 16' x 4' AGP. I have been using the 3 in 1 tabs from walmart for sanitizer and the shock they sell. I also have added their sanitizer and algicide and have used 3 jugs of the pH down trying to lower TA(using areation between doses of pH down) I went to the pool store and told them I added the shock first per the instructions before sanitizer and he asked me what I was shocking if there was no sanitizer. Are there any stickies explaining to me what shocking is?
Currently my levels are:
Testing with the HTH 6 way strips:
TH - 400
FC - 0
pH - 7.8
TA - off color
CYA - 30-50
Testing with the HTH 6 way drops:
TC - 0.5
pH - 7.5
TA - 280
TH - 540
CYA - I do not understand the disappering dot. It never dissapears.
The water is cloudy with no color. No burning in the eyes and yesterday, the FC was 10. Not sure what to do to keep chlorine in. Like I said, I am using the 3 in 1 tabs by HTH for sanitizer but would like to switch to using BBB. Can I just switch to that method?
