Seachem Alkaline Buffer 4Kg is a non–phosphate buffer to raise pH and alkalinity (KH) and buffer with Seachem 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. Seachem Alkaline Buffer raises pH and buffers between 7.2 and 8.5. It is gentle, safe, and enhances the freshwater environment.

Directions: To increase pH, use 1 teaspoon (6 g) for every 80 L (20 US 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 Dosage Calculator.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.
