We just got them in today and the first thing we thought was "REEF TANK."
It's running without a heater (no room) so it maybe limited to what can be kept in it.
If you set one up in a warm room it should not be a problem.
The light puts out alot and the colour is very nice.
Theres not much room for error in a setup like that. If something dies your in trouble. The only other problem I can see is salinity changes because of evaporation.
Should be interesting seeing how it does. I may set one up at home next to the computer.
