Product details

Seachem Alkaline Buffer 300g (236) is a non-phosphate buffering additive designed to raise pH and alkalinity (KH) while helping stabilize carbonate/bicarbonate buffering in freshwater aquariums. It’s intended for planted aquariums and for very hard water situations where phosphate buffers may contribute to algae growth or water cloudiness. Using carbonate/bicarbonate chemistry, it buffers water in a target pH range of about 7.2 to 8.5, supporting a more consistent freshwater environment. It can also be paired with Seachem Acid Buffer as part of a buffering approach for managing pH and alkalinity.

Features:

  • Non–phosphate buffer to help avoid phosphate-related algae/cloudiness concerns
  • Raises pH and increases alkalinity (KH) using carbonate/bicarbonate buffering
  • Buffers water to a pH range of approximately 7.2–8.5
  • Designed for planted aquariums and for very hard water where phosphate buffering may be undesirable
  • Buffers with Acid Buffer™ as part of a pH/alkalinity management routine
  • Described as gentle and safe for freshwater use
