Fountain Bowl Biological Filter Kit (Round & Square)

The Fountain Bowl Biological Filter Kit is a powerful yet hidden filtration solution designed specifically for Aquascape fountain bowls. Available for both round and square bowls, these kits include mechanical and biological filter media that sit discreetly inside your basin, filtering water as it flows through your decorative fountain bowl.

Each kit is engineered to fit securely beneath bowls of specific dimensions—32" or 40" diameter and 27" or 33" square—while remaining completely hidden from view. The system provides essential filtration to remove debris, improve water clarity, and promote beneficial bacteria growth to support a healthier, clearer water feature.

Easy to install and service, these kits are ideal for decorative fountain bowls, pondless water features, and eco-friendly landscapes.
