I have a gunite pool with a SWG that's just gone through its second season. When it was opened in the spring I had a massive scale problem. I got rid of it all with a couple of no-drain acid washes but I want to ensure I don't have a repeat performance.
What pH should I shoot for before they turn off the pump and close it down? 7.2 or should I go lower?
TA 80 (working on lowering it a bit)
