I just completed the installation of a refugium. I started with a reef octopus 24 wide, back of the tank hanging refugium. I removed the tabs from the side and the bottom. I built a stand to elevate it so I wouldn't have issues with the return and drilled the sump for the pump and return. We had thunder storms all weekend, they made me nervous with the new holes in the sump. It would have gotten real deep if we lost power, The generator couldn't have been started quick enough. :rain:
