Am I shortening the life of my vinyl liner with these levels?
Test Kit - TF100
I just switched from PB to the DIY BBB method and I'm concerned about the FC, TA, and CYA levels for a vinyl pool. The Pool School recommends, FC 3-7, TA 70-90, & CYA 30-50.
I'm slightly higher than recommended & I know that lowering the CYA will allow me to lower the target FC, but I'd like to try and let the CYA lower on its own and not drain & replace 12-14K gallons.
