Seachem Alkaline Buffer 300g
Directions for use:
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). 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.
