FC nothing. Not sure how to test
Used Taylor k2006 kit
Had husband drain 1/4 of pool and CYA still 90. This was 2 days ago, and he is too busy to drain more right now (I have no idea how to drain it myself). Because pool turning green, I panicked and I just put 2 gal of liquid chlorine in after throwing in two large caps of PH Plus. I know I am wasting chemicals, but I am determined to master the mystery of caring for the pool. Help this novice idiot please.
