I put an elbow into the waterfall box too, and add a standpipe of about 3-4". This keeps the box fuller, which increases the down pressure so the water from the little holes doesnt push back up.

Are you thinking about installing a check valve to stop the problem? We ended up having to put one on ours because of the position of the bulkheads draining too much into the sump and found it was a nice, easy, cheap and quick solution.
I'm very excited to see how this tank turns out.
