Green & Cloudy Water

[aylad]

The fact that you have a CC of 3 means that your chlorine is killing off something in the pool, and that your beginning chlorine level after the shock had to have been higher than the 25 that you were expecting. Total chlorine = Free chlorine + Combined chlorine, so you must have started at TC of 27. What you're going to need to do is maintain that shock level until you see the pool clear up, and your CC goes down to 0, in addition to not losing any chlorine overnight.

How are you testing your water?

Yes, Watermom, I backwash once a day. It appears to be working fine now - since having it serviced and repaired. The pressure rises a little, not a lot, and then drops back down when I backwash.

Aylad, I use the test kit I got from Ben to do my testing. If I just need to stay at it, then I can do that. I just expected to begin to see some changes by now and thought I must be missing something.

I'm thinking of putting in a skimmer sock, just to see if that will help any, but I guess I'll just keep pouring in the bleach until it clears, unless anyone can see something I might be missing.

[Watermom]

Yes, try the skimmer sock and keep hammering it with bleach. Also, you don't need to backwash every day. It is best if you don't. The rule is to backwash whenever your filter pressure rises 8-10 psi over clean filter pressure.

I didn't know that about backwashing, Watermom. Thank you for your help and I'll just keep at it with the bleach and will add the skimmer sock. I'll let you know when it's sparkling in the sun. :-)

Just to add to what Watermom said, a dirty filter will actually filter water better than a clean one--less space for junk to get through....
