It works seamlessly with Seachem Acid Buffer to target specific pH levels between 7.2 and 8.5, ensuring a crystal-clear, algae-free environment that supports all freshwater life stages.

## Description

Alkaline Buffer™ is a non–phosphate buffer to raise pH and alkalinity (KH) and buffer with Acid Buffer™. These buffers are designed for the planted aquarium or for very hard water where phosphate buffers may pose an algae or cloudiness problem. Alkaline Buffer™ raises pH and buffers between 7.2 and 8.5. It is gentle, safe, and enhances the freshwater environment.

Review: excellent product no effect on ph - a must have for remineralizing RO water for aquarium use… very effective and does not effect ph… highly recommended.
Review: Je m'en sers pour reminéraliser mon eau osmosée lors des changements d'eau. Répond parfaitement à mes attentes. Il faut juste veiller à bien diluer avant avec de l'eau osmosée, sinon ça peut faire des petits "paquets" qui vont mettre plus de temps à se diluer dans le bac. Et il faut bien veiller aussi à ne pas humidifier le produit et donc utiliser une cuillère ou tout autre ustensile parfaitement sec.

## Questions & Answers

**Q: How many gallons does this 600 grams treat?**
A: I HAVE A 55 GALLON AND IT WORKS GREAT BRINGS UP THE PH WITH NO PROBLEM WHEN THE WATER US YELLOW PUT IN TWO TEASPOONS AND IT DOES THE JOB

**Q: How long does the desired ph last in the tank? A day ? A week ?**
A: Hard to say, I did a 20% water change every week. This product makes the water higher in pH.

**Q: Does this need to be used at every water change or top off??**
A: I use it after water changes but I always check the KH of the water before adding the product. It is very powerful stuff so I suggest following the directions on the back. I try to keep my KH around 4-6 along with my GH. I would not put this in every time you top off.

**Q: I used too much seachem alkaline buffer and now my kh is too high. how do i remedy this other than a water change?**
A: You could add Seachem acid buffer to bring it down.  Most use the two together to get to correct alkalinity & ph desired.  See Seachem website for amounts to use if both buffers.

### ⭐⭐⭐⭐⭐ Review
*by 3***S on 12 November 2025*

Our water is a little on the soft side, and we love our shrimpies, so we use this product to maintain a comfortable hardness level for them in developing their exoskeletons. It's easy to use, not messy, and works on its own when used as directed, so there's no need to keep adding a little more. We drop it into some dechlorinated, treated water during routine water changes so it can dissolve before hitting the aquarium. It has made our lives easier and our shrimp are strong and healthy!
