I love my test kit! This morning's number are: FC=10, CC=2, pH=7.2, TA=110, CYA=30.(Originally FC=0,pH=7.4,TA=100,CYA=0 on 7/23) FC dropped by 3 over night. Water still cloudy. Pool Calculator advised add bleach & baking soda, which I faithfully did, in prescribed amounts. Will continue fighting the good fight So thrilled to have found you guys, am telling everyone who will listen & some who don't, about your site. Looking forward to a trouble free pool!
