Hey guys just wanted to see how everybody felt about the Lifegard Aquatics Quite one pumps. I need to get a new pump for a 90 gal tank so I was looking at the 4000. It's right at 991gal/hr so I think it would do well. I want to mount it externally and I really want a quite pump since it's in the same room as the TV. Anybody out there have one of these?
