OK, here is a good test for you. Been trying to find out the brand or origin for this skimmer for some time, but no luck. It is a dual beckett and works pretty good. Has a gate valve on the exit, so easy to control the level. I have a mag 18 driving it. Produces as much skimmate or more than my Vertex In-280 which I use on my other tank. Only downside is the beckett one takes a lot more power. Advantage is that the neck and cup needs less cleaning with all the air and bubbles that go through there. But the gunk that ends up in my collection bottle is as stinky and thick as ever.
It is an old one, though, and can't find any clue to what brand it is.
