Seachem Acid Buffer is a non-phosphate buffer for lowering pH in planted aquarium. It does not trigger algae or water cloudiness in phosphate-rich hard water.

Seachem Acid Buffer is used in conjuction with Seachem Alkaline Buffer. Both buffers are suitable for planted aquarium or for very hard water where phosphate buffers may pose an algae or cloudiness problem.

Seachem Acid Buffer lowers pH and buffers between 6.0 and 8.0 when used with Seachem Alkaline Buffer. As Seachem Acid Buffer lowers the pH, it converts carbonate alkalinity (KH) into available CO2, usable by plants for photosynthesis.

DIRECTIONS

To lower pH, use 1/4 teaspoon (2g) for every 80 L (20 US gallons) daily until desired pH is reached (this dose lowers alkalinity by about 0.2 meq/L (0.6 dKH)).

Larger doses may be required in very hard (KH) or alkaline waters. For precise dosing, use the Seachem Digital Spoon Scale.

In order to adjust pH gradually, or if water is soft or not well buffered, use Acid Buffer with Alkaline Buffer. When using Alkaline Buffer and 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.

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