Seachem Alkaline Buffer
Adjusts pH to 7.2—8.5
Increases alkalinity
Contains no phosphate


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.


To increase pH, use 1 teaspoon (7g) for every 80 L (20 gallons) daily until desired pH is reached (this dose raises alkalinity by about 1 meq/L (2.8 dKH)). For precise dosing, use the Seachem Digital Spoon Scale.

In order to adjust pH gradually, use Alkaline Buffer™ with Acid Buffer™. When using Alkaline Buffer™ & Acid Buffer™ together to target a specific pH, utilize the suggested ratio chart.
