Seachem Acid Buffer is a non-phosphorate buffer to lower pH and buffer with Alkaline Buffer.

Both buffers are designed for the planted aquarium or for very hard water where phosphate buffers may pose an algae or cloudiness problem.

Acid Buffer lowers pH and buffers between 5.0-8.0 when used with Alkaline Buffer.

As Acid Buffer lowers pH it converts carbonate alkalinity (KH) into available C0².

Suitable for use in freshwater aquariums and ponds.

To lower pH, use 1/4 teaspoon (2g) for every 80 L 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.
