Aquaponic systems are generally completely closed loop systems that keep the fish closely sequestered and often in quite dense populations. But the technology is great for many applications that aquarists can enjoy. One outgrowth of fish keeping is the outside pond or water feature in a garden. These are often used to house a variety of goldfish and Koi, but can contain food fish if push comes to shove.
An aquaponics garden for pools is not such a stretch and this video shows how one can be constructed quite cheaply. The climate will often determine if this is a wise choice to spend resources, since the unit should operate the entire year. Pools that are shut down for winter will have quite a problem providing enough consistent wastes to grow the plants. In this case, the aquaponic garden for pools is to be installed in Australia, so the climate is conducive.
Most of the parts are gathered locally, and the wood for the frame often can be found used. The only real specialty item is the actual bell siphon that controls the water in the grow bed. As mentioned in the video, it can be built from scratch easily enough, but is probably better to be properly constructed to ensure proper operation over time.
Retrofitting aquaponics garden for pools
Unlike most established aquariums and other reservoirs for fish, it usually quite simple to retrofit and aquaponics garden for pools into the existing water feature. All that is really required is a place fore the grow box to be located and the water lines to bring the water into the grow box and then allow it to return to the pool .
The design possibilities are endless and so are the materials you might want to incorporate. The only real limiting factor is that the grow bed should be raised up above the pool. This is much more convenient to do any gardening chores in the grow bed anyway, since there will not be any bending required.
If you are already keeping fish in a garden pond, why not consider adding an aquaponics garden for pools to your backyard?
