LF: someone to build a hang on tank refugium

[cbrine]

I'm not sure if this will offer any hell, but I was able to find a guy in Medicine Hat who made a DIY a hob refugium using an aquaclear filter, and cut up the tray thinger to keep the chaeto inside the filter and painted the outside to keep the light from spreading and bolted a small puck light to the top to ensure proper lighting. I've seen videos on YouTube of people using a larger size with great results. Maybe an option if you can't find exactly what you are looking for...
I can send you picture if you would like an idea.
