Phosphate Minus - Aquaforest

Aquaforest - Phosphate Minus

The Aquaforest Phosphate Minus is high-quality phosphate and silica removal media that can be used in a fluidized reactor for fresh and saltwater tanks.

Phosphate Minus will remove phosphates and silica from the aquarium, leading to overall better water quality and a reduced fuel-source for algae growth. 

In freshly set aquariums it prevents occurring high phosphate levels and in matured aquariums, it reduces PO4 levels and stabilizes water chemistry.


  • 25-100 ml per 100 l (27 US gal) of water
  • Phosphate Minus should be placed in media reactors with a suggested water flow of at least 400 l/hr.
  • It’s also suitable for a passive use in filter socks.
  • Phosphate Minus should be replaced every 4 weeks or during a significant rise of phosphate levels in the water.

Shortly after placing it in a filtration system, the product may slightly colour water.

Although Phosphate Minus should not be rinsed before use, brown dust is an active phosphate remover and is completely harmless for the aquatic life.

Brown colouration of water will disappear after a short time and rinsing the product in a RODI water will lower its efficiency.
