Thanks Janet. I have put in 4 lbs of stabilizer ($25) and still can't keep chlorine. Been adding a gallon every night. I have some pucks left over from last year before I switched to BBB, so I bought a floater at Walmart today and will try that route for a few days. Hate to waste more $$ on pool store conditioner since I have the trichlor. I know...got to watch the ph while using the pucks. Taylor kit from Amazon should be here today or tomorrow and I will post full set of numbers. I'm out of regents on old Walmart test kit, but last check (5 days ago) for CYA the dot never disappeared. Good news is water is cyrstal clear!
