Glass Baffles

[mling]

That can work, kind of like a remote refugium. I'm kind of confused on your setup though, it the 45 gallon tank with rock in it, your sump? The glass baffles are for not only separation but to stop bubbles from getting into your return section minimizing bubbles in your DT. Also with my return I cut a notch out of my overflow so I could run the black loc-line tube under the water level and low enough to put egg crate over the tank. What are you using for a return pump?

 

My sump is going to become my refugium. This is why I have the skimmer in a different location. So the next step is to get some cheato, live sand, etc.
