Webb's BioClean F3 is a biological filter media engineered to create the ideal environment for beneficial bacteria to grow, thrive, and continuously renew. Its protected internal structure provides safe zones for both young and mature bacteria colonies, allowing healthy bacteria populations to develop and replenish naturally.

As water flows through the filter, BioClean F3 supports the biological filtration process by converting harmful ammonia from fish waste into safer nitrates — helping maintain clear, balanced, and healthy pond water.

How It Works

BioClean F3's unique multi-hole design maximizes surface area for bacterial colonization. The protected internal channels shelter developing bacteria from hydraulic disturbance, ensuring a stable and resilient biological filter bed — even during backwashing or high flow conditions.
