Fauna Marin Ultra Phos Phosphate Remover Media

Phos is a new activated aluminium based adsorber which safely removes phosphates and humic substances from the aquarium.
The pollutants are bound to the surface of Phos and will not be released again.
Phos can maintain very low nutrient concentrations in your tank. Unwanted algae growth will be stopped and corals will show their natural colors.
