Thanks for your advice. Unfortunately I've tried brushing it off and it's not coming off. Hopefully when I get the pH balanced that might help?

I looked at Michael's formula but it asks for liters (I guess since it has an L) not gal and it want's to know another fact that I can't remember at the moment that I never seem to know either.

If I'm using the BBB method, where do I get the CYA? At a pool store? And do I ask for cyanuric acid or some brand name?

Thanks.
