Pool water is green

[PoolDoc]

Adding insufficient chlorine repeatedly tends to be useless against established algae . . . even when you use more in total than would have been needed in one dose to kill the algae.

We need dimensions, an accurate volume, and a trustworthy CYA reading.

However, if you're in a hurry, and not too concerned about a lightened (or bleached) liner, in the EVENING add 10 gallons of PLAIN 8% bleach in a SINGLE dose. Follow that on succeeding days with 6 gallon doses each evening UNLESS your OTO shows an ORANGE chlorine test result.

The accurate volume for our pool is 23,800. I feel you are getting frustrated with me but I am trying to do my best in getting information. Believe me --I am beyond frustrated. Our pool liner is already lightened -so I am not worried about that. We are on water restriction in our town and I will not be replacing the liner this year for sure. Once again-thank you for your help

Not frustrated, just wanting specific answers. But, I was kinda pushing back against the urgency you felt, and emphasizing that a reliable 'fix' requires specific accurate info from you. I end up doing that fairly often.

It's sorta like a doctor saying, "Yes, yes, I'm sorry it hurts. But WHERE exactly does it hurt, and WHEN did it start hurting?"

If you're not worried about bleaching, use the chlorine bleach as suggested.
