I started this project a few weeks ago and have been making slow, but steady progress.

Here's where I'm at:



It's two layers of 45 gallon sterilite containers for the fish tank and two halved 30 gallon containers for the grow beds.

The pump is a mini jet 606 and the beds drain through bell siphons. There's a large air stone in the tank for aeration. System is a bit loud, however it's in a spare bedroom, so it's all good.

Next step is to get some hydroton in the beds, then put gravel and clay pots in the fish tank and let it cycle some more...
