Product Information




Seachem Alkaline Buffer 1.2 kg (2.6 lbs)

Seachem 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.

DIRECTIONS: 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)). If water is soft or not well buffered, use with Acid Buffer (see below).

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. If using with RO or DI water for a water change, then use with Acid Buffer at a fixed ratio (see chart) to set the desired pH.

Once pH is set add water to aquarium as soon as possible to avoid pH fluctuations (for best results, base ratio on weight of product added).
