Always Watching
I'm not sure on the trade. But I was thinking about madgap's waterfall suggestion. Then it occurred to me, why not have one side overflow into the otherside. Then have a strong pump or canister filter, with the intake on the low side and the output on the high side. Then you would have a continuous waterfall and you could adjust the hight and flow to what ever you like.
. The only things I would do is use a more natual color gravel and put something inside the center box, so you can't see in there
