I ran a VS2-24 on my 120g reef when I was first setting it up. It worked great for me on a Mag9.5, but I ended up changing my sump setup and changed skimmer as well. It was great when I didn't have a consistent water level in the sump, performed just as well when the water was high or low. I was very happy with it, virtually no maintenance ever.
I think you'll enjoy yours for sure. That'll be plenty of skimmer for a 55g tank.
I got a VS2-24 as well. It has been set it and forget it for me. The only problem was when there was a power outage. It would overflow my collection cup. I think part of my problem is I'm using too big of a pump. I got a Gen-x 40 supplying it. I'm switching it out with a bigger skimmer that I have yet to decide on.
