We Install The Aquascape Ecosystem


An ecosystem pond works with Mother Nature to provide food, shelter, and safety to the wildlife around it. It also provides you with an all-natural, low-maintenance piece of paradise. It’s important to remember, however, that every piece of the ecosystem puzzle must be present in order for a true ecosystem to be in place. Eliminate one of these elements and you’ve got an unbalanced ecosystem that won’t be so low-maintenance anymore. Check out the things you’ll need to get your ecosystem pond fired up.


In order to have a successful water gardening experience, you must think systematically and understand the critical role of each ingredient in Mother Nature's recipe.

• The fish nibble on the plant life (and everything else), including the algae.

• In turn, the fish produce waste that, along with other forms of natural debris, falls to the pond's bottom.

• Debris is broken down by the aerobic bacteria and the other microorganisms colonized on the rocks and gravel all over the pond bottom.

• Once broken down, these substances are absorbed as nutrition by the plants.

• The plants grow and are once again nibbled on by the fish ... 'round and 'round it goes, infinitely.


So, in a naturally balanced water garden, you have this never-ending aquatic circle of life where all parts complement the others and play critical roles in the pond's natural born harmony. Contact us to learn more!
