I'll second the Euroreef suggestion. I've literally tried just about every major skimmer on the market, and came back to the Euroreef for its ease of use, efficiency, and simplicity. I've been using a CS6-2 for several years now and am very happy with its performance. With such a light stock load, you really don't need a beckett skimmer anyhow.
BTW, 10 lbs of live rock is a bit little. I'd recommend another 30 lbs or so, and let natural processes do some of the filter for ya.
