Those aren't bioballs their ceramic rings, but anyways turns out the mag drive 5 is actually a mag drive 3. But at 4' 200 gph is good enough for a 55 gallon right? If I used a filter sock and just put a bunch of ceramic rings in the sump, would I really need baffles? Wouldn't the filtration be the same? I'm thinking some like this *Red is return line, Black is overflow line
