Felix and I have planned our aquaponic system. We are using a steel wire rack as the base. We will have a 20 gallon fish tank with two 10 gallon (36″x18″x6″) grow beds for a 1:1 fish tank to plant bed ratio. We will use a Four outlet power relay module to control the pump, grow light and fish food. This relay module will the control center of the operation. With this we can control remotely when the plants are watered, receive light and when the fish are fed. We are currently in the process of procuring everything we need for the project.
Here is our working Instructables tutorial
