Okay. This thread has convinced me to get one of these little cubes.
What would you get, Kiran, the 20-C or 25-C (if you could find them stocked somewhere)?
I've got a bunch of Red Sea Nano Filters, some 13W Fluval lamps, pressurized CO2 and such. Thinking of going high-tech with a couple little cubes because they'll be easier to trim than another giant tank.
