Thanks I didn't want everyone to think I was going against what to do. But since it's been this long I felt I had to try something.The potential downside to clarifier is that over time it could build up in the filter and cause you to need to change out your sand. Probably not the end of the world, and it's only a maybe thing, so in your shoes and after so long, I'd give it a shot myself, even if I wouldn't normally use it.
Yeah that weather sounds about right but maybe alittle hotter in July and August. And maybe just a few days here and there that we get that coldI am glad I am not the only one with concrete cracking around the coping of the pool! Yours isn't nearly as bad as mine, but I am guessing Ga doesn't have -10 degrees in January, and 99 degress in July!
