I am running three smaller tanks - two thirty gallon tanks plus a 40-gallon breeder. All of them have SPS. I am running three different hang-on skimmers at the moment - a Bermuda Aquatics Rogue, a Deltec MCE600, and an AquaC Remora Pro.
My Remora Pro is a back-up to another Bermuda Aquatics Rogue that I have. I needed to clean the Rogue and have not gotten around to re-installing it. My Remora Pro is actually doing a pretty good job, but they can be hit-or miss.
I recommend the Bermuda Aquatics Rogue. They are a bit on the large side, but they do work well. My Deltec MCE600 is running on a tank with no fish, so the bioload is pretty low. Therefore, I have not yet witnessed what the MCE600 can do.
What is your budget? You may be able to find a deal on a used hang-on skimmer, too.
Mark (skimmerwhisperer) will have some good recomendations for you.
