Why are u so rude? Do you know anything about Borates? I suggested he check into Borates not that he has to do anything! Fyi, FACT, SWG can cause higher PH, FACT, Borates take oxygen out of water which will help stabilize PH and algae needs oxygen to live. I would suggest people to look into Borates to see if it's for them, BC I have a sparkling clean pool for 2 yrs and it works!
The forum has studied Borates extensively.
