CH: 0 for the past ten days. PH: 7.2. ALK: 128. CYA: 30. SALT:4800. Water temp: 90 degrees. Air temp: low 90's.
I've never experienced this problem before. I've checked to make sure there is good flow through our 3 CG cells. I cleaned the cells with HA. The water is clear but I don't like the CH being zero for so many days.
My only other thought is to add another 30 pounds of CA. My question .. can one put too much CA in a pool? Any other thoughts on what to check?
