Hi everyone, first post here. I'm trying to set up a 15 gal tropical community tank in my living room. The problem is that its on top of a bookshelf, right against the wall, so I can't hang a filter on the back. I don't have any place to hide a canister since there's no cabinet. I'd rather not do an UGF. So, any ideas? What i've come up with so far is maybe siliconing in a piece of glass to make a false back and building some sort of biofilter behind it with a powerhead or something. I know I'm not the first to do something like this, anyone have drawings or pictures or even a link to get me started? I'd like to keep the heater hidden too, if at all possible, although not as high priority as the filter.
