Yeah sorry did loose sight of that.
Well there are pod breeding kits that you can get on line and you could do this in say a 10 gallon tank, heater, filtration, and pod piles or regular liverock rubble, sand substrate and some culerpa which they love to play around in. It would be like having a nano tank with no fish or corals, not that a mushroom or two wouldn't look nice. You will need only some flake food to feed the tank with which will go a long way and last a long time. You would not need special lighting.
You could even ask your LFS to see if they could provide you with some pods that may be stuck in their filters or other local reefers. They would be best caught before lights on in the morning.
To me it would be as simple as that, and you could use a turkey baster to collect some pods in the morning to feed to your main tank.
Sound ok?
