First Test Results

Thanks, Chem Geek, for your reply.

I just tested my CYA and it is 65.

I'll post my FC reading tomorrow morning.

Thanks for the added info. Since you have CCs you have something in your pool that's combining with some chlorine and also causing cloudiness. IF this is mustard/yellow algae, then it will require (at your CYA level) about 35 ppm FC to get rid of, but see what happens at your current FC level first since you didn't report any mustard yellow dust/dirt like substance. Also, be sure to keep the pool uncovered during the day and have it exposed to sunlight. I'm betting that you are just still in the last stages of clearing the pool from regular algae and it should clear soon if that's the case.

Thanks for your reply, Richard.

The FC reading was 23 this am and the TC was 23.5.

I don't think I have a yellow/mustard algea problem. Its clearer today than it was yesterday.

Can the high TC level cause cloudiness? Will the pool become clearer as the chlorine levels come down?

Thanks,

Paul

No, the high FC (which is what makes the TC high) should not cause cloudiness (at least not by itself -- chlorine can raise pH and that combined with high CH and TA can cause cloudiness, but that's not your situation). I suspect it's just clearing up the last of the algae or other organics that have been in the pool. Just keep circulation running and keep the FC high until it's clear, then let the FC drop, then adjust the pH (if needed) and have fun in your pool!
