Building Process

Cut a hole in the center of the bucket lid with the utility knife. The hole should be slightly smaller than the diameter of the 3/4 inch PVC pipe.
Cut a piece of the 3/4 inch PVC pipe about 12 inches long. This will be the standpipe that will hold the plant grow bed above the water level.
Make hole near the bottom of the standpipe with the 1/4 inch bit. This overflow hole will prevent the water from rising too high in the grow bed.
Insert the standpipe through the hole in the bucket lid and secure it with silicone sealant. Make sure there is no gap between the pipe and the lid.
Cut a piece of the 1/2 inch PVC pipe about 18 inches long. This will be the inlet pipe that will bring water from the pump to the grow bed.
Attach the PVC reducer to one end of the inlet pipe and the PVC elbow to the other.
Cut another piece of the 1/2 inch PVC pipe about 6 inches long. This will be the outlet pipe that will return water from the grow bed to the bucket.
Attach the PVC tee to one end of the outlet pipe and another PVC elbow to the other end.
Drill holes along the outlet pipe with the 1/2-inch bit. These holes will make water drain back into the bucket.
Assemble the inlet and outlet pipes with the standpipe, as shown in the picture below. Use some silicone sealant to seal all the joints.
Fill the bucket with water and plug in the pump. The pump should have a hose that fits over the reducer on the inlet pipe.
Fill the space between the standpipe and the bucket lid with gravel or clay pebbles. This will be your plant grow bed where you can plant your seeds or seedlings.
Add some fish to your bucket. Please ensure they are compatible with each other and your water temperature and pH level.
You can harvest your plants when ready and feed your fish regularly.
