Peat Balls are an ideal biological filter medium, commonly used in "black water" aquariums.

They effectively and safely reduce the pH and hardness of the water (gH).

Humo should be used in aquariums with discus and cardinals.

Thanks to its large active surface area and cleaning bacteria, Humo provides excellent biological filtration.

The use of active carbon in conjunction is not recommended.
