Building an Aquaponic System

Aquaponics is the combination of aquaculture and hydroponics. In aquaponics, the nutrient-rich water that results from raising fish provides a source of natural fertilizer for the growing plants. As the plants consume the nutrients, they help to purify the water that the fish live in. A natural microbial process keeps both the fish and plants healthy.

Step 1 Acquiring the Materials

To build this system you will need to construct two grow beds, two fish-food growing tanks, a fish tank, as well as a stand to elevate the fish food tanks.

To build the grow beds you will need:
5  8' 2x4s
1  4'x8' sheet of 1/2'' plywood
4  8' 4''x4'' posts
8  3/8'' carriage bolts with washers and nuts
555' sq. of pond liner
2'' deck screws
small grade pea gravel
2' permeable bags (coconut fiber bags and vermiculite)

To build the fish tank and fish-food tanks you will need:
2  55 gallon drums (plastic)
1  little giant 200gph submersible pump
2' sq. of metal mesh filter
8' of 3/4'' flex hose
small grade pea gravel
1  1'' 8' PVC pipe
6  PVC fittings
2  90 deg. PVC fittings
1  'T' PVC fitting

To build the stand you will need:
Scrap steel (we used 3'' steel pipe)
Welder
Grinder
Spray paint

looks great... i have a couple of white drums like that and was considering using them as they were with a lid on top - couple of questions;
-- dont quite get what you mean by having to cut a hole out of the fish tank to " allow oxidation" ?
--i am assuming only the bottom tank has fish in it>
-- what do you feed the fish>

cheers

How many Rock Bass do you put in the lower tank? Do you start with more fingerlings and then thin them out as they get bigger?
