What is an Ecosystem Pond?

According to dictionary.com an ecosystem is “a system formed by the interaction of a community of organisms with their environment.” Well, that sounds a little bit complicated, but it really does not have to be. At Cole’s we believe no matter what size pond you are trying to create it needs to be ecologically balanced or an Ecosystem Pond.

“a system formed by the interaction of a community of organisms with their environment.”

An ecosystem pond works with nature to create a low maintenance retreat for you while also providing food, shelter, and safety for wildlife in the surrounding area. An ecosystem pond is made up of five essential components:

  1. Circulation System
  2. Filtration
  3. Fish
  4. Aquatic Plants
  5. Rocks, Gravel, and Bacteria

It is crucial for each one of the components to be present for the ecosystem to be effective, without one of the components it will fail. Please check out the all the components in more detail below.
Circulation System

The circulation system is simply the pond geek way of saying pumps, hoses, and fittings. Pump and piping size are crucial to the health and aesthetics of your pond. Moving water provides oxygen for your fish and helps keep the pond clean!

Proper Filtration

We believe that pond should include both mechanical and biological filtration. Mechanical filtrations mostly come in the form of skimmers and acts as a pre-filter while also providing housing for you pump. Biological filtration provides surface area for the colonization of beneficial bacteria which helps remove excess nutrients from the water.


Fish are often seen as a dreadful part of having a pond. This is one the HUGE MYTHS about ponds Fish are actually an essential component of the ecosystem, as they will feed on string algae and other debris from the bottom of the pond.

Aquatic Plants

Not only will plants add life, colour, and texture to your pond they are mother nature’s best filter. Pond plants pull excess nutrients from the water, eliminating algae’s source of food. Plants are crucial to the overall health of your pond.

Rocks, Gravel, and Bacteria

Rocks and Gravel covering the bottom and walls of your pond is a relatively new idea. Rocks and gravel provide amazing aesthetics benefits and also protect your liner from UV break down of your liner. Rocks and gravel will also provide more surface area for beneficial bacteria to grow on which again will aid in the breakdown of excess nutrients and debris.

There it is, it is that simple – five components coming together to give you functional beautiful pond. Follow this five part recipe and you find you are created a new lifestyle getting you are your family.
