Check out the New Aquascape Pond Components designed to simplify installation Maximize Surface Area, and make Cleaning the Filter Easier than Ever!

A wetland filter is a modular, up-flow constructed filtration system mimicking the natural processes of a wetland. Engineered for outstanding water quality, this system is modular, making it scalable for a wide variety of pond sizes.

How Wetland Filtration Works

1 Snorkel Vault

Provides a central access point for cleaning and maintaining the wetland filter.

2 Snorkel Vault Lid

Protects the Snorkel Vault from debris entry, withstanding foot traffic for safe use

3 Centipede® Module

Distributes water evenly throughout the wetland filter bed for maximum contact with filter media

4 AquaBlox® Water Storage Modules

Act as a settlement chamber, allowing solids to drop out of suspension before the water rises through the filter media.

5 FilterBlox™ Modules

Use internal Biological Filter Tubes to maximize surface area, greatly increasing capacity for filtration

6 Centipede End Cap

Provides a convenient connection point for incoming plumbing

Sizing Wetland Filters

Determine the Surface Area of the Water Feature that the Wetland will Filter

Measure the Surface Area of the Pond

Max Length x Max Width = Pond Surface Area

Use the Correct Target Wetland Surface Areas Below to Target Optimal Wetland Size

Pond Type	% of Pond Size
EcoSystem Pond	5 to 8%
Recreation Pond	12 to 25%

Use 100-250 gallons per hour (gph) per AquaBlox or FilterBlox (Approx 380-950 Liters per Hour)

*Filter Size reflects components only; surrounding backfill excluded

**Note: Listed Liner dimensions contain only the wetland filter and backfill and do not include any liner needed for
outflow into the pond.
In most installations, a larger liner will be required to accommodate outflow
as well as outcroppings, plantings, and boulders around the filter.
