I just put this skimmer together using a bulb sleeve at Homedepot in the lighting aisle. It come in 4 ft clear tube for about $5-6. I cut it to size and use a clear plastic tube as riser into the hole of the sleeve. Then i fashioned a medicine bottle cap as a collection cup. Add a valve to increase /decrease bubbles if you like.
Sorry for the crappy pic.
