I’ve used pH Up for several weeks now and it works consistently. The water stays clear and the pH stabilizes well. No cloudiness even after multiple adjustments. Great for maintaining a balanced environment in my aquarium.

It’s easy to use and effective. I added a small amount each week to keep my pH stable. The liquid is colorless and doesn’t affect water clarity, which is a big plus.
