Phospha-Guard Bio-Cubes 500ml – phosphate removal

Phospha-Guard Bio-Cubes is a phosphate-reducing medium for reef aquarists who want to lower phosphorus load between water changes. It is meant to be used together with Nitra-Guard Bio-Cubes, and the two products form a single dosing system for the aquarium.

Why it matters

• The formula contains no iron compounds, so it does not add iron to the water.
• The manufacturer describes the product as non-toxic.
• The bacterial biomass that develops in the medium serves as food for corals and filter-feeding organisms in the tank.
• No regular replacement or dosing is required once the product is established, and the manufacturer states that it can postpone the need for water changes.
