Hey just the person I want to ask some questions to! Out of curiosity does your skimmer cup drain ever get clogged while going to the skimmate locker?
I'm wondering is the swabbie ever gets chunks that floats up and over into the cup.. To eventually clog the drain?
I havent had any issues with the drain becoming clogged at all. Not sure if the CS-1 has a smaller drain port than the CS-3, but I'll snap a picture of my setup when I get home so you can compare. The only real "issue" that I see with the swabbie & skimmate locker combo is that the thicker "tar" can build up in the bottom of the cup and create a ring around the drain hole. This creates a lip that the skimmate has to overcome before going down the drain tube. Which basically equates to having some (very small amount) of skimmate in the cup at all times. If you clean the cup more frequently than I do (about once a month) then you likely wont ever see this issue.
A recommendation I do have if you decide to build your own locker - do what the avast marine guys did and route the "output" of the locker through a container of carbon. My locker is a 5 gallon IO plastic bucket and when its full, I cant smell it in the fish room at all until I take off the lid. The carbon "muffler" for lack of a better term makes a HUGE difference.
