I couldn't use a waste collector, which was a big deal to me. There were like 4 other ideas I wanted to employ, and the guy told me no to every one of them. I can't even remember what those ideas were since it was over 10 years ago. The one thing I did like about it was that the venturi drew air from the collection cup. So you never smelled skimmate. That was great, but it wasn't enough to keep me using it.
How often are you trying to take your skimmer out for cleaning? I do it about two times a year, and the pumps about three times a year.
