The high porosity of ceramic substrate creates an optimal environment for the growth of beneficial bacteria, which play a crucial role in the filtration process. Acting as both a mechanical and biological filter, the substrate captures and consumes large waste particles resulting from excess food and fecal matter in your aquarium, effectively reducing the toxicity of these substances.

Key Features:

• Creates biological stability in your aquarium by providing the ideal environment for beneficial bacteria
• Biological, mechanical filtration attacks the waste produced in your aquarium
• Suitable for cannister, internal and wet/dry filters
• Comes with a FREE netting bag
