I though i’d throw this one out there. I had a tough time building a refugium in ny waterbox 100.3 sump. I found this ice cube holder on amazon and converted it. Fits perfectly in the back. Superglued the egg crate before the lip and drilled in the drain holes. I have a tunze ecochic refugium light. I also cabled tied it to keep it from expanding and breaking the superglue. Cost about $20 without the light. Pumping in from the out on my uv. Works great.
