I want to set up a 3gal nano reef tank (possible slightly larger, up to 10gal). I want the system to be as aesthetically pleasing as possible, namely by keeping any equipment out of sight. Could I just drill two holes in the tank, and use a powerful external canister filter, to filter the water and provide water movement? Or is a seperate powerhead necessary? In addition, is there an external way of heating the water, without the use of a sump? Thanks a lot.
