I'm in the Process of setting up an Octo Tank, and was wondering if there is a way I can run a Skimmer with no Sump below the Display Tank. I've heard the only way to run a Skimmer externally is by having it above the water Line. My issue is that the Tank is a Unique Shape, and there is no way I can accomodate a sump into the stand below the DT, but I would have room to have a skimmer Only. Any Ideas?

I don't think so, unless you have a return pump on the skimmer. The reason it needs to be above the water line is because after it runs through the skimmer it's going to be draining downward. You can't fit a 10 gallon tank in your stand?
