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 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.
