BioCliff 1 L

BioCliff is an OASE biological filter medium made of natural siliceous rock. Its highly porous structure offers a vast colonization surface for beneficial bacteria that break down nitrites and pollutants, for healthy and clear aquarium water.

Key features

• Natural rock with a very large bacterial colonization surface
• Grain size of 5 to 15 mm: extends water contact time in the filter
• Fits into all common filters, as a supplement to other media
• Contributes to crystal-clear and stable water

Usage tips

Place BioCliff in the biological compartment of your filter, after mechanical filtration (sponges), to prevent it from clogging. Rinse it only with aquarium water to preserve the bacterial colonies.
