Hello, just as the subject says my pool is eating a ton of bleach. I'm a new owner to this pool which was built back in the 1980's. It's an inground pool located in Phoenix, AZ. So keep in mind we have extreme desert heat here and the average ambient temps now are 105 during the day and upper 80's to low 90's at night. My pool temp is 92 degrees currently. I haven't owned the pool long enough to wonder if it's just the heat eating through the bleach or if something else is wrong. My numbers are pretty solid, yesterday I ran a full test of everything and today i checked my FC and it was down to 1 already.
25,300 gallons in ground, plaster
FC - 1 (I try to keep this at 6 if possible)
CC - 0
TC - 1
pH - 7.5
T/A - 110
CH - 230
CYA - 50
Temp - 92
I have a pentair sand filter and my water is currently crystal clear. A week ago today we had that giant haboob come through and cake the phoenix area with 2-3" of dust. My pool has finally recovered and it's back to clear. Could the sand in my filter be bad and need to be changed out? I have no clue the last time it was changed but it's doing its job just fine. All the rest of my numbers seem to be in check except for my chlorine usage which is nearly a full 184oz of bleach daily, i'm using the 6% Walmart stuff. Maybe it's just living in the desert and extreme heat, no clue? Thoughts anyone? My pool gets sun pretty much all day from sun up to sun down with no shade and it's always sunny here in AZ.
