Concept makes sense although I question how much actual difference they would make because of the tiny volume. Not sure I'd want a transparent muck collector on display in my tank thoughAlso, quite a while back, you told me about some sponge filters at Amazon. Have you seen these sponge filters yet? They have cups below the sponges to hold bio balls. Interesting concept and the reviews are mostly positive. What do you think about them?
