I have gone through the shock process two separate times this year. The first time everything went fine, but it got to the cloudy stage and after a week or so it was still cloudy, even with backwashing. I added Clear and Perfect clarifier and it royally messed up everything. The water didn't clear but actually started to go back towards green. Last sunday I began again. Raised the shock level to 28, somehow I couldn't get it to 30. Brushed twice a day, backwashing daily, running my Dolphin pool cleaner to get what I can't see at the bottom, and praying.
It's Saturday and I'm at the cloudy phase again. I have been at this stage since Wednesday. My FC was at 38 at 6:42 pm last night (a little before sundown) CC was 0 and FC at 36.5 and CC at 0 at 7:52 this morning. Everything is still cloudy. I know it takes sand filters up to a week to filter out, but what about the shock level. Do I stop adding bleach and let the FC come down to normal, or should I continue to add the amount of bleach I would for regular maintenance? I've searched, but can't find an answer. Plus, I really, really want the water to clear up more quickly and I ready in another post that someone with a sand filter added DE to the skimmer. What was that about? I have never read about that. What is the process, does it work, and could it work for me? I know people wanted to swim for Memorial day, but with it so cloudy and FC so high it's looking like that won't happen. Help me or come shoot me, though I prefer the first.
CH 80 (person at the pool store said CH only really matters if you have a concrete/plaster or whatever kind of pool, not vinyl is that true?)
