Elo500 Posted November 15, 2014 Report Share Posted November 15, 2014 My RO with salty gh at 6dh is ph6.5. I'd like to raise a 5g bucket to phi7. The instructions for Benibachi Golden pH-Up say to add a spoon to tank wait 24hr and measure....very vague, there is no spoon in the bag so how much raises ph how much? Anyone use this?

jumpsmasher Posted November 16, 2014 Report Share Posted November 16, 2014 I think the recommended dosage is 10g per 15/20 gal so maybe add one or two gram at a time and test your water after 24hr and see where it is at and how much it raises it.
