A few days ago, I was getting >0 CC readings and was trying to figure out what to do. So I took a step back, got my other numbers in order, and let the pool sit for a day. Did nothing.
So here's what I did yesterday. Water is crystal clear, BTW. And CCs went to zero went I let it go. (I sorta wanted to see if they would burn themselves away.)
Water temp around 70 degrees. 28k gallon vinyl lined inground pool
YESTERDAY
8am - FC 0, CC 0, TA 100, CYA 50, PH 7.2 ---> Added 2 gallons of 12%
9am - FC 3, CC 0 ---> Added 2 gallons
11am - FC 7.5, CC 0 ---> Added 2 gallons
2pm - FC 9.5, CC 0 ---> Added 2 gallons
4pm - FC 13, CC 0 ----> DID NOTHING
7pm - FC 8, CC 0 -----> Added 1 gallon
8:20pm - FC 13, CC 0 -----> DID NOTHING
TODAY
7am - FC 9, CC 0, TA 100, CYA 50, PH 7.2 ---> Added 1 gallon of 12%
8:30am - FC 12.5, CC 0
This is an AWFUL lot of chlorine for a crystal clear pool with no CCs. When I go outside and walk around the pool, you catch whiffs of chlorine. But if I stick my hands in the water, and gather some up, I don't smell anything from the water itself. Should there be any smell whatsoever from a perfectly maintained pool, with appropriate FC?
I did buy an aquarium ammonia test, which on the day I was letting the pool sit, gave me a reading of 4. But from what I have found, I'm not sure how valid that is.
(As a side note, I bought a large batch of chlorine that was manufactured in March, and it seems noticeably less filled and smelly, than the new batch I bought 2 days ago, manufactured in late April. So I suspect the FC rise isn't predictable due to varying potency.)
What's going on?
Thank you
