This is my new skimmer. It is an ETSS Sump Buddy 40. I have had it running for about 4 weeks and it has performed very well. This is nice because it uses very little room in my sump. The skimmer has a piece on the side that slides up and down to adjust the height of the bubbles. It is very easy to get to and easy to adjust. I am using an older pump I had lying around that is rated at 900 GPH at 0 head. I am getting about 800 GPH with the added PVC. I will post more updates as time goes on. At this point I would recommend it to anyone looking for a new skimmer rated up to 180 gallons.
