Alkaline Buffer is a non-phosphate buffer designed to raise pH and alkalinity (KH) and buffer with Acid Buffer. These buffers are designed for the planted aquarium or for very hard water where phosphate buffers may pose an algae or cloudiness problem.
Alkaline Buffer raises pH and buffers between 7.2 and 8.5. It is gentle, safe, and enhances the freshwater environment. What distinguishes Alkaline Buffer from other buffers is that it does not contain phosphates. This makes it ideal for the planted aquarium, where excess phosphate could contribute to undesirable algae growth.
