Seachem Alkaline Buffer

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 Buffe raises pH and buffers between 7.2 and 8.5. It is gentle, safe, and enhances the freshwater environment. Alkaline Buffer is a sodium bicarbonate based buffer.

Features:

• Adjusts pH to 7.2—8.5
• Designed for use in planted aquariums
• Increases alkalinity
• Contains no phosphate

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)).

In order to adjust pH gradually, use Alkaline Buffer with Acid Buffer. When using Alkaline Buffer & Acid Buffer together to target a specific pH, utilise the suggested ratio chart. 

This chart is based on use in RO or RO/DI water and ratios may need to be adjusted for use in tap water.

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.
