Been reading and learning a lot here the last 30 days but have a few questions. Have really struggled with this pool the last couple years...then I found you guys and want to try the BBB method. First the specs...Pool has approx 8500 gals now. Thought it smart to save on chlorine with the 3/4 full pool. Started about 3 weeks ago with this...test from the pool store. Bought a TF-100 test kit since.
Green. Covered for part of the winter. Had a winterball in it, I know better next time.
Added Borax to raise PH to 7.5 then 12.5% chlorine to 10 ppm and a couple trichlor pucks in a floater I already had from last year (thinking it would raise the cya up). I have checked twice a day for almost 3 weeks bringing the chlorine back up to 12. Every morning morning and evening it's down to 2 ppm fc. Last night put a whole jug in which should have raised it 15ppm according to pool calc (awesome tool btw). Ran the pump on low power 24/7 for the first 10 days or so. Running on high power 24/7 since.
This morning MY testing shows...
Greyish blue color
? CYA (too low)
I was shocked by the CC and PH since I had not been testing it since the SLAM isn't over. I did it this morning just out of curiosity. Was headed to town any way so I took along a sample.
Pool store tests...
1. Was told that chlorine works better at lower PH/Alk... since my FC is low should I adjust those back up before continuing SLAM?
2. Should I raise the CYA up to 30 now and use more chlorine or wait till after SLAM is done. Thought the pucks would have done more for that.
3. Is the water cloudy due to the TDS level? Would adding fiber or DE be wise?
4. I have a bottle of floc laying around from last year. Would this help settle the TDS/dead alge and vacuum to waste?
5. Is "Clean Shock" (Sodium Dichloro-s-Triazinetrione Dihydrate) the dichlor listed in the pool calc options? Want to use the right rate.
Thanks in advance for your help.
