I am a new pool owner and I am having trouble keeping my chlorine levels up. Our pool is approx 25,000 gallons and is in the direct sun, with no shade all day.
We got our house about a month ago and prior to that the house was empty, it was a foreclosure, I'm not really sure if the pool was being taken care of while it was empty...
After reading on this site how to care for a pool I decided that I would test and adjust my chemicals on a weekly basis. The first time I tested the FC level was 0. I wasn't too worried about it because I wasn't sure when the last time chlorine had been added. I added 160oz of 6% bleach, the following week I tested the chemicals and again the FC level was 0, I again added 160oz of bleach.
So, I thought that I just needed to add chlorine more often, so I decided that I would test every day for the next week to see when the level dropped that way I would know how often I would need to add more. The next morning I was shocked to find that the level was again at 0! So I added another 160oz, the next morning FC was still 0. So then I doubled the amount and put in 320oz, the next morning the FC was at 4, this only lasted one day, the FC was at 0 the next morning.
I have tried using different test kits thinking that I was testing something wrong, I had the water tested at Leslies and they came up with the same results. I thought maybe the pool was bigger than estimated, but whenever I add muratic acid to adjust the pH it adjusts as it should for the amount added. The CC level has always been 0, so to my knowledge there is no bacteria in the pool.
The pool looks great, crystal clear. The water is not irritating to the skin. The CYA level is 60, which seems to be a little on the high side but the pool is in the direct sun all day. I have read a little about chlorine lock but the there are a lot of mixed reviews and I am not sure what to believe.
The pool store told me to drain 1/3 of the pool and tried to sell me a bunch of expensive chemicals. Any suggestions on what to do?
Here what my chemicals are at today
FC=0
CC=0
TC=0
pH=7.8
TA=110
CYA=60
Calcium hardness=480
