My house came with a spa which doesn't get used much so I decided to convert it into an aquaponic system. I mean why not, the tank and pump are all there, the fence keeps the dogs out. All I had to do was put a 40mm T piece in and then run a 4 way hose connector up to the first pipe. The four way allows for future expansion and flow control. The 90m down pipe with holes and clay ball trough is all pretty self explanatory.
I initially had a hose run off back into the spa but this was not enough to cope with the throughput so I added more pipe
I then laid out my seeds in a rockwool grow tray, which I water with seasol, and let my inner geek create a spreadsheet of it (the little flag is A1)
Our first visitors are 10 redclaw we pulled out of Pine dam at the weekend.
