600 Grams (1.3 lbs)

Seachem Alkaline Buffer raises the pH and alkalinity (KH) of your aquarium water and holds it steady between 7.2 and 8.5 - an ideal range for most freshwater environments. Alkaline Buffer is safe,gentle,and phosphate-free to reduce the risk of algae or cloudiness.

  • Raises pH and increases alkalinity
  • Buffers pH between 7.2 and 8.5
  • Great for planted aquariums or very hard water

Seachem Alkaline Buffer is a sodium bicarbonate-based buffer. This makes it slightly less stable than phosphate buffers,but better suited for planted aquariums where adding more phosphates would lead to an algae problem.

300 grams (10.5 oz): Treats 860 Gallons
600 grams (1.3 lbs): Treats 1,720 Gallons
1.2 kg (2.6 lbs): Treats 3,440 Gallons
4 kg (8.8 lbs): Treats 11,640 Gallons

Directions: To increase pH,use 1 teaspoon (7g) for every 80 L (20 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.
