In the chat-room yesterday there was a bit of a talk about filters and that got me thinking, which one is best? I'm also asking, because I'm looking for a new tank for Christmas, and that would help me a lot to know what to look for!
Some of the tanks I looked at had some sort of plate atop of it, where all the sponges/biorings/etc. are going and I don't know is that a good idea?
So - post your thoughts please and help me decide
Oh, and I'm looking for something around 200l (roughly 52 US gallons) and I believe this might be deciding in choosing the right filter.
