Thanks so much!
We went to Leslie's and had it tested:
Free available chlorine 2
Total available chlorine 2
Ph 7.5
Total alkalinity 80
CYA 0
Calcium hardness 180
Total dissolved.solids 600
Phospahtes 200

They recommended adding CYA, otherwise said all else was fine. Though he did say we should run the filter 24/7...we usually run four hours at night. He said since its new sand it may take a few days for the water to clear up. We bought some bleach, will add it when we get home.

Anything else?
