Thanks AnnaK and PoolDoc. Yes I am located in the middle of nowhere. I do have some of the standard store bought chemicals on hand like stabilizer, PH up, PH down, calcium chloride, floculant, Trichlor tablets and 1# bags of Dichlor “shock”. I wish I would have found this forum several hundred dollars ago. Looks like the bleach may be my only option right now. I will be ordering the K-2006 test kit soon. Right now I am using a basic OTO drop test kit and HTH strips. When I get the CYA levels up should I add 30 gallons of bleach at once or a period of time?
