Hi everyone. I have owned a pool for 3 years now and never had this problem. My pool will not hold chlorine. I use bleach as my chlorine source. Here are my specs:
Ph: 7.8
TA: 80
CYA: 60
CH: 210
FC: 0
CC: 0
Phosphates: 1000 ppb
So far, I have added 968oz of 7.6% available Clorox Concentrated Regular Bleach at once through the skimmer at 9PM. It brought my levels up above 5ppm (my kit does not read higher than that). I woke the next morning, around 7AM, and still had above a 5PPM (again, my test kit does not read higher than that), and then by later afternoon, the chlorine levels registered at 1.5PPM! By the next day, all gone and back down to 0. (This was 1 week ago)
Tonight at 9PM, I added 1,452oz of 7.6% available Clorox Concentrated Regular Bleach through the skimmer. I have a good feeling that by evening tomorrow, my chlorine will read 0 again.
Pool water is only very slightly cloudy, but blue.
We haven't used any pucks in the floaters because of our high CYA levels.
Any help you can offer?
Plaster pool, In ground, 18000 gallons, PentAir FNS Plus 48 SQ Ft DE Filter, and a Pentair 3/4 Whisperflo Pump.
