Hi JBonnette and welcome to the forum!

Tricia is right that it takes a few days to filter out dead algae, but resist the temptation to add any clarifiers or flocs. Usually adding more stuff is not helpful and will delay clearing the water. Give your filter time to do its job. Run your pump 24/7 and watch the pressure on your filter. If it rises 8-10 psi over your clean filter pressure, you'll need to backwash.

Regarding your cya --- there is no way a test can give a cya reading of 9. That test is just not that sensitive. Test it yourself and repost with a reading.

A question -- do you have a calcium hardness reading? Your cloudy water is most likely due to dead algae that needs filtered out but since you say you are using cal-hypo, just thought I'd ask. A high calcium reading can also cause cloudy water.

By the way, thanks so much for becoming a subscriber. We appreciate the support. Hope you find the forum helpful.
