Would be a cool project, I often think about it while walking the dogs at the beach. I'm sure you could use an old bar fridge to make a chiller of some sorts, the hard part would be controlling it so it keeps the tank at a constant temperature. Given the critical nature of it (in terms of life support) it may be better not to skimp on it?

Thirty odd years ago there was a person down here who built one from a fridge for that exact project and it worked very well. The fridge coils were on the back of a stainless steel plate and the thermostat started a pump that pumped the water over the plate untill the temperature dropped. He had a little occi in there successfully for quite some time (amongst other things).

A school of Stellus Artoisii and a nice breeding pair of Corona Cerveza would look great.

I've wondered before if you could diy one of these into an aquarium cooler, probably not powerful enouf for a 600L tho, there are dirt cheep, might be good for a nano...

from what ive read about that id agree only really good for a nano as most of them are peltier type http://en.wikipedia.org/wiki/Thermoelectric_cooling

there are lots of diy peltier coolers but most would only be suitable for a nano also they also draw a lot of current and can be troublesome. if you were to buy a refrigant powered water cooler you would be well on your way to owning a proper chiller for the money it would cost. if you are big into diy an evaporative cooler could be a go but you would for ever be topping
