...in my 10400 gallon AGP. Last weekend I had a nice neon green pool and a chlorine level of 1PPM so I added right at 3 gallons of bleach as instructed by the pool calculator. The next morning the water still had a greenish blue tint (i didn't check the numbers) but I added almost 3 more gallons of bleach. That afternoon I had the water tested at Ace and the FC was 18. CYA has been 40-50 the entire time. The problem is every day for the last week I tested the water (TF-100) and my FC is staying at 16 (32 drops before clear). My pH is 7.2 and my CYA is still 50. I've been running the pump 24/7 and backwashed twice, why won't the FC go down? I'm concerned for my liner with the FC so high for long. The water looks great though! Any ideas?
