I was thinking of adding an eheim external to my tank, and apparantly the tubes will fit under Juwel tank lids at the back pretty easily.
I've used a fluval filter in the past, and found it was temparemental to start - furstrating, but it always started in the end. I think eheim externals have bigger volume of filter media than Fluval externals, and are slightly cheaper.
