Mary,
That's not the procedure. That will get you into a see-saw of ph and Alk. I'll bet you've been raising pH with soda ash--pool store's "pH Up" or something similar. Soda ash raises alkalinity, Borax doesn't
HOWEVER, Alk moves with pH so when you lower pH with acid then raise it with Borax, the Alk will move with it. Soda ash is worse, because each time the Alk will be higher.
So go to the Alkalinity forum and read Ben's directions for lower alk.
Aeration is the key--it's the only way to raise pH without the Alk rising too.
