Well, I tested it tonight and the chlorine was down to 2 the ph was down to 7.4 (according to the drops) and the stabilizer on the test strip dropped to the appx 100 reading on the strip. This is 24 hrs after I put 3 gallons of bleach in the pool (6%). For that matter, I put 3 gallons in the night before too. Should I wait to test in the morning to see where I am at or add more bleach just to be safe?
