Its internal placement and suction-cup setup let you secure the unit within the habitat.

How does the Zilla filter clean and circulate water?

Patented filtration technology cycles water through the filter to clean it and improve water quality. The included carbon cartridge is designed to remove odor, waste, and debris, combining water circulation with filtration in one unit.

• Designed for use in an aquatic reptile terrarium.
• Water cycling helps move habitat water through the filtration system.

How does the filter help with biological filtration and animal protection?

The Bio-Holster cartridge holder encourages beneficial bacteria for biological filtration, while the protective grate helps keep animals from entering the filter unit. These features support filtration within an aquatic habitat while adding a barrier around the unit.

• The Bio-Holster is the cartridge holder for the biological filtration setup.
• The grate is positioned to help prevent animal entry into the filter.
