The Aquascape Large Snorkel® Vault and Cap provides an easy way to clean wetland filtration systems. Simply lower a pump down into the vault for quick and simple cleaning. Wetland filtration is designed to help strip excess nutrients from the water, tackling issues that commonly plague large-scale water features. The vault also reduces the need for costly and invasive dredging. Four optional ports for Aquascape Large Centipede® Module attachment are included to allow installation in a wide variety of applications. The vault can also be easily retrofitted into existing ponds, and the included cap allows the top of the Snorkel® Vault to be easily concealed and hidden from sight.
