having trouble with a cloudy pool

[Watermom]

TR-140 with about 900 lbs of pool sand. Its a big one.

No kidding! That's huge!

I'm surprised your water is not cleaning up rapidly. Definitely, do the DE test. I'm wondering if you got low quality filter sand -- or even sand that's NOT filter sand, such as coarse sand blast sand.

I used pool sand from home depot (I believe it said #20 on the bag)... http://www.homedepot.com/p/Quikrete-...5350/202314677 thats all i could find on their website, i cant remember if this is the exact type I bought.

However, the pool was cloudy even before the sand change... I thought the sand change would help.
