The Aquascape Large Snorkel Vault and Cap provides an easy way to clean your wetland filtration system. Wetland filtration is designed to help tackle issues that commonly plague large scale water features by helping to strip excess nutrients from the water column. The vault also reduces the need for costly and invasive dredging. The Snorkel Vault contains four optional ports for Aquascape Large Centipede Module attachment. Measuring 47-inches in height, the snorkel is easily retrofitted into existing ponds and the included cap allows the top of the snorkel to be easily concealed and hidden from sight. Aquascape is passionate about the products we produce, providing unique products, designs, and features that stand above the competition.
