Hello all,
So we have been using bleach 6% for about 2 months now. (we did use the 3" pucks for the first few months recommended by pool builder) And are having a hard time maintaining the TC at 4.5 our CYA is a little high 50.
I guess here are our pool details:
21,000gals
Plaster
new build finished 03/2018
Pentair Clean and clear 520 cartridge
Pentair 3.0HP/3.95 SFHP with Booster-Rite
Spa
and auto filled with RO water (reverse-osmosis)
We tested every day this weekend and had to add 4ppm of chlorine to our pool everyday. So I did a full test yesterday (9/23) to try to figure out where the Chlorine was going.
Here are the results
FC-1. CC-.5 CYA-50 ph-7.5 CH-500ppm TA-80
So we decided to SLAM it and added 880oz of bleach last night around 9PM. Tested it this morning at 8:30am and we are at FC-.5 and CC-1 with the k-100 test I got TC- .5 to 1 range and ph 7.5. I added 175oz of bleach this morning.
We need some direction on what to do now. Should I have shocked it again to 20ppm and added the 880oz again this morning? Our water is clear never been green but we assume since TC always went so low we must have some kind of invisible bacteria in there.
Please any help is greatly appreciated.
Thanks,
Dora
