Seachem Acid Buffer

Adjusts pH to 5.0—8.0 Designed for use in planted aquariums Converts carbonate alkalinity (KH) into available CO2 Contains no phosphate Acid Buffer™ is a non–phosphate 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 6.0 and 8.0 when used with Alkaline Buffer™. As Acid Buffer™ lowers pH it converts carbonate alkalinity (KH) into available CO2.
