Phospha-Guard Bio-Cubes is the world’s first solid carbohydrate based phosphate remover that naturally removes phosphate from both freshwater and seawater. 

Unlike competing products that use heavy metals to remove phosphate, Phospha-Guard Bio- Cubes uses Redfield’s Ratio to remove Phosphate. Using this all natural method gives far greater performance over competing product. Unlike pellets, Phospha-Guard Bio-Cubes is a “pointof- source” treatment which prevents system crashes occurring. The biomass created by Phospha-Guard Bio-Cubes contains no ferric oxide / hydroxide and is completely non-toxic. In fact, the biomass created by the heterotrophic bacteria is also a great source of nutrition for corals and other filter feeders such as clams. 

Phospha-Guard Bio-Cubes requires virtually no maintenance and does not require an expensive fluidized media reactor to operate.

500 ml treats up to 174 gallons depending on Phosphate Levels.
