Poolhelp,

John's advice on pH is good to follow.

I am assuming you cannot test for CC's. You would be wise to get a kit that will do that.

I would test at dusk this evening and add enough Cl to bring it back up to 15-17 if your pool is vinyl...25ppm if your pool is plaster or Fibreglas.....calculate and add Cl accurately.

Test again tomorrow AM...before the Sun hits it too hard. If you've lost more than maybe 1-2ppm, you are still killing organics in your pool.

The solution to that is to keep adding Cl back up to those levels above over and over 'til the pool clears. A struggle for now, but you'll find it well worth the effort.

Cloudiness in pools can be from a variety of causes but your test results indicate that Chlorine is the answer to clearing your pool.

Remember to lower the pH....I'd shoot for 7.2
