I have been trying to balance out my PH and Alk.
My Ph is testing at 6.9-7.0 and my Alk has been 270-320 and I am struggling to get them balanced. I have at 3900 gal Metal Frame AGP. I have been adding the Muriatic Acid to drop the Alk. How much of this can I add in a day? I have been adding about 2 cups at a time.
I have also been having problems getting the PH higher. I have tried Borax and PH up and it just doesn't seem to hold it up. I was able to get my Alk down to 230 but then my PH dropped to 6.8. What am I doing wrong?
