Seachem Alkaline Buffer

  • Adjusts pH to 7.2—8.5
  • Designed for use in planted aquariums
  • 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, and safe, and enhances the freshwater environment.

To increase pH, use 1 teaspoon (6 g) for every 80 L (20 US gallons) daily until the 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.

HINT: First determine the amount of Alkaline Buffer™ needed for the volume of water. This should be determined based on your desired alkalinity (KH). Then, divide by the number in the middle column to obtain the correct amount of Acid Buffer™ required.
