In MD, the pool is open for only 3 months. Afterwards, more than 1/2 the water is drained.
If I'm replacing the water every season, do I need to worry about CYA and pH? The reason I ask is that I have a bucket of Omega Chlor Sticks 99.3% Trichloro-s-triazinetrione (Tri-Chlor), which raises FC and CYA and lowers pH.
I'm guessing that people use this in MD because water is being replaced every year?
