cloudy water!

I don't know about the PH, but the best guess chart will tell you that if you have a CYA reading of 135, you should maintain a FC reading between 8-15 PPM. Yours is only 3.0.

You've gotten good advice.

First: Shock your pool to 25ppm. Yeah, 25ppm. Use bleach or liquid chlorine. I'd keep it there for a couple of days, then let it drop to the 8-15 range--AND DON'T LET FC DROP BELOW 8! I suspect a new algae bloom.

Second: Stop using sodium carbonate to raise your pH and switch to Borax--20 Mule Team Borax at the grocery store.

Third: Make your adjustments slowly. Don't try to do it all at once.

Fourth: Are you chlorinating with cal-hypo? If so, that can cause cloudiness. Stop and switch to bleach or liquid chlorine.

Thanks for the responses, but I 'm wondering how I could be having an algae bloom when my water is crystal clear and blue? The reason I keep my FC level @ 3.0 is because I also use an ozonator. Is this a mistake? Do I really need to keep it at 8.0 or higher?

All the "pH up" options in my pool store are sodium carbonate, what is Borax and why do you reccommend it instead?

Thanks,

Steve
