sanj said:I had seen some reference to these filters not long ago on an american site. I dont think I would use these filters in a display tank, but they look like they could be a good possibilty in the likes of breeding tanks.
What is the great thing about them though? It seems to me more about the large area of media for biological filtration and that they are relatively cheap.
