Wow, thanks for the response back so far guys.

FC = 3.0
CC = 3.0
TA = 90
Ph = 7.2
CYA = 50

I have a 10,000 gallon pool with a circular cartridge filter. The filter is relatively new, I bought it at the begining of spring. I wash the filter every other week.

So I should shock the pool by adding bleach to around 15 ppm and keep it there until the CC are at 0. I should keep the pool running 24/7 until that time.

I will do this tonite. Anything else??
