The Aquascape Centipede® Modules sit at the lowest point of the wetland filter and helps to efficiently remove sediment, decreasing maintenance and increasing water quality. Wetland filtration is designed to help strip excess nutrients from the water, tackling issues that commonly plague large-scale water features. Wetland filtration is the most scalable pond filtration system, capable of filtering even large lakes when scaled up correctly. For these systems we recommend contacting a CAC (Certified Aquascape Contractor). The Centipede® Modules are modular in design and works on both earth-bottom and lined ponds, allowing for installation on a wide variety of projects. The Centipede® Module can be retrofitted into existing ponds and is ideal for use with the Aquascape Large Snorkel® Vault and Cap.
