Hello, everyone.

I have a 22 x 40, 45,000 gallon rectangular in-ground pool. It has a Jaccuzi Sand Filter and a Polaris 380. The pool has a LOOP-LOC Mesh Safety Cover that has been patched. I don't think the patches are holding, because the water was black when we opened the pool.

Its been almost two weeks and the water is a light green color and I can't see the drain in the 10 foot deep end. The Polaris is not filling up and the basket in the pump housing has been clean for a few days now.

Here are the pool's "stats" after being tested this morning:

Saturation Index: -.052.
Free Chlorine: 3.5.
Total Chlorine: 3.5.
pH: 7.0.
Total Alkalinity: 83.
Adj. Total Alkalinity: 72
Calcium Hardness: 303.
Cyanuric Acid: 32.
Copper: 0.
Iron: 0.

I am using a 10% liquid chlorinator from the local pool store and 3 in. pucks in the chlorinator for water sanitation.

Any help you can give me would be appreciated. Thanks. Paul
