If you want to put together a rudimentary home aquaponics system that combines a filter grow bed with a continuous flow pump, this may be the way to get started. The system is a combination of a variety of flow types. The grow bed is filled with Hydroton expanded clay pellets, but the water is delivered in a continuous flow. There are lots of ways to put together a rudimentary home aquaponics system, this may just be one of the simplest ones to create.
This may be the best way to get started, it requires nothing that is exotic or difficult to obtain. You will need an aquarium. In this case it would be best to ensures the unit has a plastic frame on the top so that the grow pan can rest on it without putting any direct stress on the glass edges themselves. Besides the aquarium for the fish, you will need a food grade grow pan, inert growth media to fill it, a pump and hoses to connect the system and distribute the water in the bed.
This rudimentary home aquaponics system seems to be designed to use natural light. If that is your case, this is a great retrofit for a nitrate filter for a small display community fish tank. As long as the system is designed to provide enough light to the fish for their needs and you are not interested in keeping underwater plants as well, this can effectively remove nitrate from a standard set-up.
The system only requires a single pump, some standard smooth filter hose to connect the pump to the grow bed and another loop to provide the spray bar the distributes the nutrient rich water from the aquarium into the rudimentary home aquaponics system grow bed as evenly as possible. The water is allowed to flow back into the aquarium underneath by gravity flow. The spray bar is made by punching holes in a loop of filter or hydroponics hose on the inside of the ring. The draining is done by punching holes in the bottom of the grow bed and resting the unit on the rim of the aquarium it is filtering.
A Rudimentary Home Aquaponics System that can be Modified to Suit
The video gives a good idea of how this system can be easily created with minimal tools or equipment. It is truly a rudimentary home aquaponics system that can have a number of modifications done to it to make it even more effective. A grow light, such as suspended HO or LED system can be added above to make this a system that can be used anywhere indoors. The grow bed can be the only filter for the fish, or an air stone can be added if there is not enough
