What FilterBlox Does: Provides massive surface area for beneficial bacteria to colonize and multiply Breaks down harmful nitrogen, phosphorus, and organic waste naturally Creates clearer, healthier water without chemicals Reduces maintenance by processing waste more efficiently than gravel Supports aquatic plants in wetland filter systems Key Features: 441% more biological filtration surface area compared to traditional gravel beds Includes 60 pre-installed HDPE Biological Filter Tubes for immediate use Open, structured design ensures even water flow throughout the module Optimized for easy cleaning during maintenance pump-outs Modular and stackable design fits virtually any wetland layout Same size as AquaBlox Water Storage Modules – Small for easy integration Works seamlessly with Centipede Modules, Snorkel Vaults, and all Aquascape wetland components Why FilterBlox Outperforms Gravel: Traditional gravel wetland filters provide limited surface area and can become clogged with debris over time. FilterBlox Modules use specially designed internal tubes that create exponentially more surface area in the same space, allowing beneficial bacteria to work more efficiently. The open structure also makes maintenance easier—water flows evenly during operation and cleans more thoroughly during pump-outs. Perfect For: Wetland filtration systems Pondless waterfall filtration Koi pond biological filtration Water garden ecosystem ponds Any system requiring superior biological filtration Specifications: Dimensions: 26.5" L × 16" W × 9.5" H Includes: 60 pre-installed Biological Filter Tubes Material: Heavy-duty HDPE construction Compatible with all Aquascape wetland filter components Installation: FilterBlox Modules arrive with 60 biological filter tubes already installed, making setup fast and easy. Simply place the modules in your wetland filter area, stack as needed for your system size, connect to your Centipede Modules or Snorkel Vault, and plant with aquatic plants. The beneficial bacteria will naturally colonize the tubes and begin processing waste immediately. Frequently Asked Questions Q: How many FilterBlox Modules do I need for my pond?A: The number of modules depends on your pond size, fish load, and whether you have plants. As a general guideline, more biological filtration is always better than less. For a typical koi pond, plan for at least one FilterBlox Module per 1,000-2,000 gallons of water. Heavily stocked ponds or ponds with large koi may need more. The modular design makes it easy to start with a few modules and add more if needed. Consult with a pond professional or Aquascape dealer for specific recommendations based on your system. Q: What's the difference between FilterBlox and AquaBlox modules?A: FilterBlox Modules are designed specifically for biological filtration with 60 internal filter tubes that provide massive surface area for beneficial bacteria. AquaBlox Water Storage Modules are designed to create water storage reservoirs for pondless waterfalls and other applications. While they're the same external size and can be used together in a system, FilterBlox focuses on biological filtration while AquaBlox focuses on water storage. For wetland filters, you want FilterBlox for the biological filtration power. Q: How do I clean or maintain the FilterBlox Modules?A: FilterBlox Modules are designed for easy maintenance. The open, structured design allows for efficient cleaning during routine pump-outs. Simply reverse-flush water through the system or use a pump to backwash the modules periodically (typically once or twice per season, depending on your system). The design ensures water flows evenly through the tubes, flushing out accumulated debris more effectively than gravel beds. You don't need to remove or replace the biological filter tubes—they're designed to last for years with proper maintenance.
