All this talk of plant filtration Justin has started got me to thinking...
This unit is just an experiment, if I like the results I may make more.
I started with a 6" net style orchid pot. These are quite heavy plastic and very durable. I also used a circular scrap (cutout from a previous project) as a top, mostly to keep the roots/media out of direct light.
The pot is attached to the underside of one of the lids from my 55G acrylic growout tank. I used SS machine screws and drilled/tapped the acrylic.
I attached a PVC lift tube with a sponge prefilter. An airstone goes down the standpipe. Part of an old AC300 intake acts as a strainer on top of the lift tube.
The six inch pot is filled with Hydroton expanded clay media. The pot hangs with about one third of the media submerged in the tank. The rest of the media stays wet from water being lifted by the airstone.
Two small 2" pots hang in the lid and hold the plants.

I'll try to get some better ones tomorrow, but you get the idea.
