Hello all. New to the forums. I bought a house over the winter that has a 16x32 IG (~20,000g). The pool sat for at least 2 seasons. The pool is a bit of a pond. I have been reading the site here and getting great advice. Last night I picked up a Taylor K-2006 test kit with the FAS-DPD test. My CYA level, according to the test is non existent. Is that normal for a pool that has sat? I know I need stabilizer to bring that level back up. About how much should I need and how much should I raise it to. Keeping in mind that I will be vacuuming to waste a few times during the SLAM and replacing that water (I know its not much). Any help on this is appreciated!
