Using Wetland Filtration on Your Backyard Pond
Does your pond have sparkling clear water? If so, does it require a lot of effort to keep it that way? Thanks to the benefits of a properly-built wetland filter, it doesn’t have to!
What is a wetland filter?
A wetlands filter is an advanced form of natural filtration. Think of it as a big hungry sponge that feeds on the waste from fish and plants. Like a sponge, it is porous, allowing water to slowly pass through. Like a sea-sponge, it is alive, and it literally has an appetite for the stuff that clouds your pond water. Unlike a sponge, a wetlands is a complete ecosystem, populated by of trillions of individual bacteria, and usually, a handful of plants and invertebrates. These organisms colonize on the bottom of the pond and feed on particulates suspended in the water.
When you look at an established wetland in a backyard pond, it just looks like a shallow area with slow-moving water over fine gravel. Maybe there’s some grasses or thalia plants growing there. What you won’t see, however, is what’s going on beneath the surface that allows it to clean your water so efficiently.
