internal filter

[Riccardo1976]

I would like to install another filter in my juwel 96 tank.
I would not replace the existing filter but just add another internal one.

Any suggestions? It would be nice to have something smallish but effective

Why not get an external power filter that hangs on the back of the tank? Internal filters take up valuable real estate in the tank. Is your tank planted? If so you want a filter that doesn't cause much surface agitation.
