I'd like to add another filter to give me a bit of a back up. I'm
thinking
another cannister of some variety. Since I inject CO2 I don't want much
surface agitation. I've got about 18" vertically to work with in the
cabinet. What do folks recommend. I'd prefer it to be easy to clean like
the Magnum 350 although I don't like the outflow set up for the 350.


I use an Eheim 2028 on my planted 90g and absolutely love it.
My spraybar sits just underneath the surface aimed slightly up- provides
good water movement with zero agitation. I use the prefilter attachment to
trap any detrius before it gets to the filter- it lifts right out for easy
rinsing.
The cannister hose apparatus detatches with one lever for very easy
servicing. And it runs totally silently.
Very well designed and made.
