This undergravel filter board set includes 32interlocking plates designed to provide effective double filtration for clearer aquarium water. Made with durable, easy-to-clean materials, the filter board system fits a range of tank sizes thanks to its modular design. The eight-layer construction promotes both mechanical and biological filtration when combined with gravel and an air-driven return system.

The boards connect smoothly and securely using a buckle system for fast setup. Once installed, air is driven through the system via tubing and an airstone, helping to circulate water and support oxygenation.
