reef rig or just sump

[SeaHorse_Fanatic]

I also prefer having a sump/refugium. In-sump skimmers tend to be more efficient than HOBs & you can solve the micro-bubbles problem more easily. I hide my heater & extra live rock in there, as well as lots of macro algae. A couple of simple clip on CFL screw in bulbs (27w Phillips Daylight bulb) is plenty of light for that setup. Or if you go with a Metal halide or PC, then you can change it into a frag tank.
