Seachem Alkaline Buffer

Description

Product Description

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.

Direction

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 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 upon your desired alkalinity (KH). Then, divide by the number in the middle column to obtain the correct amount of Acid Buffer™ required.
