Nice looking tank Whiskey! I do have a question though. When you were breaking out the original overflow, do you recall what the material was? Glass or acrylic? I'm asking because I plan to update mine to filters in the sump and would like to redesign the overflow to mimic the newer design and free up some more display space. So far you've got the most "modified" waterbox I've seen. So hoping you can help.
Cheers!
