DIY: Aquaponics
- 1). Choose a system plan and select appropriate size containers for plants and fish. Plastic food-grade barrels or rubber stock tanks make good plant and fish holders. A plastic or rubber pond liner can be used with any rigid frame to form a tank.
- 2). Position the tanks so that the plant containers will drain back into the fish tank. Install drains in the plant tanks using PVC plumbing parts and PVC pipe. Drain holes should be constructed so that a couple of inches of water remain in the plant containers at all times.
- 3). Establish the fish tank before you plant the containers. Fill the fish tank with water and add the air pump and aeration stone. Allow the water to stand for at least 12 hours for the chlorine to dissipate. For faster dechlorination, use a chemical solution suitable for fish tanks or ponds.
- 4). Test the water with a test kit before adding fish. Allow time for the fish tank to become established. It may take several weeks for the fish to establish the necessary nutrient level. Add a recirculating pump, hose and timer to the fish tank. Test the fill and drain cycle on the plant tanks and check for leaks. Perform this step before adding gravel or growing medium.
- 5). Wash gravel or growing medium completely clean with fresh water before adding to the planters. Do not allow chlorinated water or dirt to drain into the fish tank. Place clean gravel in the planter, taking care to keep the drain clear.
- 6). Rinse the dirt off the plant roots. Work gently to avoid damage to the roots. Carefully place plants in the gravel. Turn on the recirculating pump to fill and drain the planter.
