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 5.0 and 8.0 when used withAlkaline Buffer™. As Acid Buffer™ lowers pH it converts carbonate alkalinity (KH) into availableCO2. It may also be used to safely lower pH in marine water.
