Pool problems.

[localfinesse]

I have been a pool owner for about a year now and I must admit that I didn't do a good job running the pool. I promised my self that I would learn the correct way.

My pool is really brown/cloudy. Here are my test results.

About 20000 gallon plaster IG pool
Hayward cartridge filter has been on 24/7 for weeks

CL - off the chart. I put 6 large bottles of bleach in yesterday (4-25-06)
PH - 7.2
Total Alkalinity - I stopped putting drops in the tester at 70 drops
Total Hardness - I added 5 drops of hardness indicator and the water started to turn blue until I mixed the water then it went clear.
CYA - About 120


I think the first thing I need to do is get the CYA down no?

Any help would be much appreciated.

Thanks

Edit:

I read the FAQ on HOWTO: Step-by-Step Guide to lowering your alkalinity.

I turned on the water fall to help aerate the pool
Should I put acid in the pool even know my Ph is low? I will hold off on putting anything in the pool until I am instructed to.
