Thanks all for the replies. The next thing on my list is actually Ben's kit. I was in the decision of it and and automatic cleaner and the hold up times on the test kit actually made me opt for the cleaner first. Just wanted to make sure before i do the drain down though. Does the sun have any effect on CYA level in a pool. I have had to keep the pool full with the hose for awhile now since we have had no rain. I was just thinking if it would lower little by little that way that i would just deal with it like that cause my #'s really are not out of the park. Just run the FC level a little higher around 6-8 ppm.
