Does anyone use the echotech's powerheads without a guard? I have 2 MP40s for my tank and they seem so 'open' that a snail or fish could easily get sucked into the head. I use a nem guard but it sure would be less intrusive if I felt comfortable that it is safe without a guard. I few years ago, I lost a blenny because he got sucked into one of my WAVs and they are not as near as open as the MP40. Anyone use MPs without a guard?
