This weekend I have added 20 gallons of bleach, and 3 boxes of 20 mule team Borax, pH is only up to 7.2 and chorine levels reached about 3ppm. I have never had a problem like this and am quite confused. Pool is a 20 x 40 IG vinyl pool. There is no slime or sliperyness, just green. Yesterday the shallow end finally looks clear and the deep end is only light green. Today I added three more gallons bleach. What happened?
OK: to clear your pool of algae, a pH of 7.2 is excellent. Let's stay with that.

I'm wondering if you have a metal problem and not an algae problem.

Please post all your numbers,
FC
CC or TC
pH
T/A
CH
CYA (VERY important to know!)
and, if possible, Cu content.

The two obvious choices are you are fighting a serious algae problem and need even more bleach to get it to shock levels

or

You have a heavy meal content that the bleach keeps making worse.

There may be a third, but without more numbers we cannot tell.
