Aquarium filter material with bio-sand

Exclusive Bio Sand Technology: Deodorizing Power Surpasses Activated Carbon!
Natural biological sand is a clean raw material, adsorption and decomposition, effectively removing odors in water and neutralizing aquarium odors.
Long-term cycle desaturation: good news for lazy people! Adsorption and decomposition continue to cycle, giving your fish a pure microecology for up to 3 years.
Stabilize water quality microecology: pH7~7.5 neutral characteristics, helping to inhibit harmful hydrogen sulfide and increase dissolved oxygen (DO) in water
Suitable for ornamental fish, place the filter material package at the bottom of the filter tank to achieve the best deodorizing effect.
