This is my upgrade protein skimmer. This is the largest skimmer I could find that would fit in my current sump - Octopus NW-200. The 12" x 12" first chamber is still a snug fit. The performance on this skimmer is good. Check out the foam head that is rising in this video.
I have high hopes for this skimmer. It is a great performer out of the box and easy to set up. I cant wait to hear the complaints about the smell when I am cleaning the collection cup in kitchen.
