Superior Biological Filtration for Your Pond The FilterBlox™ Module is the biological engine of your wetland filter system. It provides 441% more surface area than traditional gravel beds, giving beneficial bacteria the space they need to thrive and break down excess nutrients like nitrogen and phosphorus that cloud water and feed algae. How It Works Internal HDPE Biological Filter Tubes create the ideal environment for bacterial colonization. The open, structured media design allows water to flow evenly through the module while making maintenance straightforward—cleaning during pump-outs is faster and more effective than with conventional systems. Installation & Compatibility Pre-installed Biological Filter Tubes mean you're ready to go right out of the box. The modular, stackable design integrates seamlessly with Snorkel® Vaults, Centipede® Modules, and all Aquascape wetland components. Stack multiple modules to match your pond's filtration needs. Specifications Dimensions: 26.5″L × 16″W × 9.5″H Whether you're building a new wetland filter or upgrading an existing system, FilterBlox Modules deliver the biological performance serious pond keepers expect.
