I'm heading into the final phase of my planned 350 litre tank set-up. Substrate...........Sorted.

Now background features. Has anyone ever used or considered using coarse, black open cell foam for the internal backdrop? The type used in large pond filters.

It strikes me as to potentially increasing the nitrifying bacteria load. Would make an easily adaptable plant holder. Can be shaped easily and highlighted with paints if needed.

Any thoughts guys?

You could even use it as a filter, like a Mattenfilter. Should work fine, up to
but not including the time it gets hit by bad case of algae. You were planning
to clamp this on the back, not silicone it in place, right?

Those scrubber pads they use for floor scrubber, course plastic with a fair amount og space in between would work well, you can add Pellia, Moss, Java fern etc to them and they are easy to remove and adjust.

They work well in small sizes also for individual stone like shapes.

I was considering using suction pads Bill. It should add to the biological filtration. Potentially algae could wreck it of course.

None continuous is a good idea Tom. If I colour the outside of the glass black, it should give the illusion of texture without impacting on the internal space.
