Can you run it without the baskets? Right now I use the bottom basket for mechanical filtration. The other two filled with bio media. I want to know if you can run same set up with no baskets, so I have more room for bio media. If so, how would I do it?

best thing about the eheims 2026 and 2028 is how after a couple years they leak when the filter is shut off. But to each his own I guess.
