I find that I only get frustrated when I try to battle against what a particular build wants to be at a particular time. Yes, it'd be nice to have a lovely SPS reef tank with a large fish bioload in my RSM250, without aiptasia and majanos. But my broken lighting will only support softies and LPS (and pest nems), and I have two dwarf angels, so it's kind of messy and squishy instead. It's not going grace any magazine covers, but everyone seems to be happy in it, so I'm content with that.
