LOL, ok, it's borrowing an existing design
I wanted to do the UTR/wetworx, but it just won't fit within the AC300, saw this one, realized that I could built it to fit inside the aquaclear.
The collection cup is as yet uninstalled - the tube (actually an ac300 intake) is installed, but the collection cup wont be installed until the skimmer breaks in and I get a better idea where it needs to go - it will however be quite simple, just a medicine bottle with a drain.
