Green Water

[Sunshine427]

Help~~~ Yesterday my pool was crystal clear & when I came home today it is turning green. I use the Nature 2 Sanitizer, so I only shock once a month. I put Algaecide in once a week & non chlorine shock 3 weeks out of the month. Could the heat have something to do with it?? The water temp is now 88 degrees. What should I do???

To be blunt, you can't use Nature 2's imaginary chlorine levels and follow the program here. The Nature 2 puts copper and silver in your water. If your algaecide has copper in it, then you are double dosing your water on copper. Green hair problems by any chance?

What should you do? Get rid of the Nature 2, switch to polyquat algaecide, add a metal sequestrant to get the metal out of the way, and start keeping your chlorine at a safe level.

Try testing the pool water for pH, FC, CC, CYA, TA.

You really need to post your levels - also take a sample to the pool store to get tested for copper level. You may need a metal sequestering agent prior to shocking your pool with bleach.

We cannot tell you want you need to add without your test results.
