This Type of a Natural Pond System is Unique


When you get right down to it, this system is an aquaponic system. The only thing that makes it any different than most backyard aquaponic systems is the scale and the fact that it is using a swimming pool, or what used to be a swimming pool. Everything else is what a normal aquaponic system would be. Of coarse, the scale of this system gives it some unique problems as well as some unique opportunities.

In case you don't know, aquaponics combines aquaculture(fish-farming) and hydroponics(growing plants without soil) into a single system. Each system provides some of the needs of the other and eliminates problems that occur to each system individually. For a visual of a basic aquaponic system check this out.

One of the largest problems I have, because of the scale, is that to enclose the system in a greenhouse or similar enclosure is a huge task. You won't find a greenhouse of that size at your local home shop or hardware store. Ultimately, what that means is that in order to grow vegetables during winter months you will have to be creative. Enclosing the grow beds with individual greenhouses or similar coverings is what I am going to do. With such coverings, the pond will not be covered therefore the water will be subject to the cold temperatures and that will effect the fish and the vegetables.I could put the pond under a large greenhouse, but to me, that would just take away the whole idea of a beautiful pond in my backyard. By covering it up the pond will not be visibly accessible. Not really a good option for me.

Since I didn't have enough fish this winter to grow vegetables, I didn't bother making any covers for the beds. I will have them by next winter. I will construct individual greenhouse type coverings that are pretty simple to make using PVC pipe and construction plastic. I am also thinking about some type of solar heating to access some of the mid day warmth in order to keep the water temperatures above the 50F degrees it normally is during the winter.

One of the best things about this type of system is that you are free to use your imagination to create an aesthetically pleasing landscape. You can't do much with a tank and cut barrels a normal backyard system uses. Even on a very small budget, as I had, the backyard is very nice.


Problems and aesthetics aside, the main purpose of this system is to provide a cost effective alternative to a swimming pool by creating an earth friendly aquaponic system that will pay for itself in the long run. You will be able to provide plenty of organic food for you and your family with just a little effort.

  2. There is a guy who lives in my generalized area who used piping on his roof to pull of heat and moderate temps inside his house. Water from his pool is pumped into the piping that covers his roof and is redeposited back into the pool. In doing this, he is able to use his pool during the winter time as the water in the pool is always kept at a stabilized warm temperature.
