what to look for when buying a skimmer?

[ReefJunkie]

I have a 65 with a 20 sump and im running a bubble magus bm100 (rated for 100-150 gallons). I figured go bigger because I know I'm gonna upgrade eventually. I dont see any harm in 'over skimming' if thats possible.

Take approx. 23% away from manufactures skimmer ratings (no matter the brand) to get a real world value. I have my personal favourite which I can not say here since I'am not a sponser.
