thats the one i use, i just took out the filter media and added live rock to it. If you plan on siliconing, you need to allow at least 24 hrs for it to dry so that could lead up to some issues in the tank as far as filtration goes, even with the powerheads running, thats pushing it for sure. Are you considering using the berlin as the refugium? that could work, just need some live sand, chaeto, rock and a clamp on light with a CFL bulb to keep the chaeto growing.
