I've been struggling keeping chlorine in the pool, help would be appreciated. I added 4 gallons of 10% bleach in last night and today all of it seems to be gone. I've done this several times. I have checked this with TF100, also checked with a strip and it has the same results.
I should say all of these tests are from last season. I just noticed the Taylor total chlorine test slowly changed from 0.5 to 3 as it sat on the table. Maybe my old reagents are the problem?
Also about 3 week ago my CYA level went to zero all the sudden.
