Fluval AquaClear 20/30 BioMax Insert 42g — Biological filter media for AquaClear 20 & 30 Power Filters
The Fluval AquaClear 20/30 BioMax Insert (SKU: FAQ15) is a high-capacity biological filter media designed specifically for AquaClear 20 and 30 Power Filters. Constructed from porous ceramic rings, it provides an expansive surface area for beneficial nitrifying bacteria to colonise. BIOMAX nodes feature a complex pore system where beneficial bacteria can easily establish and flourish. The media shape is specifically designed to permit even water distribution, which prolongs contact time over a wider area for effective biological filtration.
This biological media helps maintain a healthy bio-filter by continuously breaking down toxic ammonia and nitrite into harmless nitrate, ensuring a stable, non-toxic environment for fresh and saltwater aquatic life.
