Seachem Acid Buffer

Acid Buffer™ is a non-phosphate buffer for lowering pH and buffering with Alkaline Buffer™. Both pads are designed for the planted aquarium or very hard water where phosphate pads can cause algae or cloudiness. Acid Buffer™ lowers pH and buffers between 6.0 and 8.0 when used with Alkaline Buffer™. As Acid Buffer™ lowers pH, it converts carbonate alkalinity (KH) into available CO2.
