Green Water - Algae?

[Watermom]

What kind of trichlor tabs do you have? Any mention of copper in them?

Hey Watermom! I don't have the container anymore, having put the last tabs in my floater. I do know the container said 99% trichlor with no mention of copper. After the problems I had last summer with daughters skin reactions, I learned to be pretty careful about additives

Sorry not to be more concrete.

How have you been keeping the chlorine high with only trichlor tabs?

About a month.

+ Dose your pool in the evening with bleach to take levels 15 ppm or higher -- 1/2 - 3/4 gallon of bleach should do it.

+ Brush your pool thoroughly the following AM.

+ Continue to dose with bleach in the PM to 15+ ppm, for 3 days after there's no green anywhere. (A gallon of 8.25% bleach will add ~20 ppm to your pool.)

I think you misread my question. I wasn't asking you how long you have been using trichlor to keep chlorine level elevated but how you were doing it. You cannot shock a pool with trichlor tabs. My recommendation was going to be the same as Ben's above. Use bleach to shock the pool.

You're right, I misread the question. I shocked the pool with liquid bleach last night. This morning, the FC was 16 ppm. The water is still greenish and there is a yellowish layer of something on the bottom.
