I’ve used pH Up for several weeks now and it’s been very reliable. My tank’s pH stays stable even after water changes. The liquid is easy to measure and doesn’t cloud the water like some other products do. My fish seem active and healthy.

It works quickly and effectively. I added a small amount after a water change and saw a noticeable pH increase within 15 minutes. No cloudiness, which is a big plus. I’d recommend it for beginners adjusting pH levels.
