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 with Alkaline Buffer™. As Acid Buffer™ lowers pH it
converts carbonate alkalinity (KH) into available CO2. It may also be
used to safely lower pH in marine water.
This is for the 300g bottle, others sizes are available either in store or by request.
