It's a Filter-Max III. I like it because it doesn't reduce flow much, but still keeps things out. That said, it is huge. With the elbow connectors it pokes out about 5" into my tank. On a larger tank this probably isn't an issue, but my 55G is only 13" front to back so this eats the bulk of the space in that corner. I'm going to try to plant around it with plants that won't clog it up, but if that doesn't work I might get rid of it.Xzavier247 said:Looks great!
Which prefilter is that?
