Seachem Alkaline Buffer

What distinguishes Alkaline Buffer™ from other buffers is that it does not contain phosphates. This makes it ideal for the planted aquarium, where excess phosphate could contribute to undesirable algae growth. Designed for raising and stabilizing pH in the alkaline range of pH 7.4-8.4. It will safely raise pH with little danger of pH shock.

Hints: Alkaline Buffer™ will not lower pH. It may be added directly to the aquarium at any time. It preferentially buffers at pH 7.8, but can manage any pH between 7.2 and 8.5 when used with Acid Buffer™ . It is gentle, safe, and enhances the freshwater environment.

A 250 g bottle treats 800 gallons.


Use 7 g (1 level teaspoon) for every 40 L (10 gallons*) daily until desired pH is reached (this dose raises alkalinity by about 2 meq/L (5.6 dKH)). If water is soft or not well buffered, use with Acid Buffer™.
