How to slowly lower super high PH

[nhager]

I’ve got a 55G tank with a PH of 8.8 or whatever api high ph test kit shows. How do I safely bring it down?

It is difficult to lower pH. Why do you want to? What is the pH of your tap water?

+1.

If I had a reason to decrease my water pH, I would use Seachem Neutral Regulator which brings the water to pH 7. You'd need to do this slowly over weeks so you don't shock the fish. Any lower than pH 7 then I'd switch to reverse osmosis water.
