This post is a brief overview of my mini home aquaponic system and how it runs on a day-to-day basis. Setting up this home system is a precursor to a larger set-up we are making and a way of learning the principals of aquaponics and how to establish the nitrification cycle in a recirculating aquatic environment.
The system is a basic flood and drain model which originally had a bell siphon to automatically drain the bed. However I have since modified it to just a small stand pipe as the roots of my plants have reached the bottom of the bed and now it only needs to flood a small amount. At the moment the pump is on a timer and set to run for 15 minutes, 5 times a day.
The video below is the system prior to beginning any growing and before I had cycled my system ready for the fish. It has a small indoor fish tank pump transporting water to the grow bed via a hose attached to a PVC pipe. This delivers water in 3 places and the water is then returned to the tank via a bell siphon which creates a vacuum and completely drains the bed once it reaches the height of the stand pipe:
And this video is after everything is up and running, with 2 goldfish and a range of plants including aubergines, basil, spinach and pak choi:
So far the the system is running successfully but the winter light has meant growth slowed significantly so I have since installed a grow light. I also accidentally overwatered the system with my original bell siphon set up and unfortunately lost the spinach plants. I think this is easy to do given the size of the system and I am hoping it will not be a problem with the larger setup we are building.
