New pool owner. 35000 gallon with Pentair ccp420 and Pentair superflo vs. I’ve followed SLAM process very closely. I used great value bleach with Cloromax type additive like my title stated (19 bottles so far) and water is blue but VERY cloudy. I didn’t realize it had additives until too late. What should I do? Will cloudiness subside?
FC 14.9 (45 minutes after adding 3 bottles)
Ph 7.6
TA 100
CYA 10 ish
CC 1.2
CH 60

FC has been dropping because pool was a swamp and cya levels are low. I’m switching additive free chlorine tonight. Filter psi was 14 immediately after getting system up and running 3 days ago and now it’s 10. Is this normal or is filter getting clogged with surfactant?

Continue the slam with 10% or 12.5% liquid chlorine if you can find it. May take a while but the chlorine will get it.

I would add 30ppm of CYA using the sock method. Without it you will burn through FC. Please print this out and read it three times...Link-->SLAM Process

To be expected, even faster without CYA.

Filter pressure will rise if it is clogged. Is the pump speed that same as when you read 14psi?

Can you fill out your signature?

Taylor fas-dpd. Dropped to 10.6 within 4-5 hours, and that 10.6 test was at 9:30 pm. At 7:30 am next day fc was 7.6. Still getting less than 30 cya reading and am almost finished dissolving 3 lbs of cya stabilizer via sock method.

The FAS-DPD test can only measure in increments of 0.5ppm or 0.2ppm. Is the 14.9 a typo?

Save yourself reagent and time and just use the 10ml sample and the 1 drop=0.5 FC accuracy.

The CYA will take a couple days to register on the test so once it’s added, just assume the new level and chlorinate accordingly.

Probably a typo. I added 74 or 75 drops, which is an outrageous amount of drops. I’ll switch to the 10ml sample, thank you.
