I've been fighting a green pool for about a week now and I'm trying to adjust my pH --- I realized that aeration was working against me for now, so I've stopped that. I've been running my filter 24/7.

My numbers at 6:30 AM today were:

Cl 12
pH 7.6
Acid called for 1 1/4 pints
T/A 160

I was feeling encouraged - my pH finally dropped after a week's worth of trying. I added 1 1/2 pints of Muriatic Acid, waited a couple of hours and added a gallon of bleach to get my Cl back up.

Then I tested again at 4 PM:

Cl 24
pH 8.0
Acid called for 3 3/4 pints
T/A 180

Feeling completely devasted about this. How could my numbers go UP? This is the first time I've ever had any experience with a pool - I've owned this one for 2 weeks and I feel like I'm really wrecking things.
