Wax, here's my idea of the skimmer. Is the airstone necessary? (additional bubbles) I'll be using a PVC Pipe for the body and my old food processor container as the collection cup.
This is a DIY from a TOTM awardee.
Problem # 1:
I can't find a good cap for the end part of the pipe. (6")
# 2
How can i make this external?
any idea, improvements, guys?
