if you do not go euro reef, you might want to look into the predator 1 by marine life aquatics. running between 270 and 300 for the base model wihtout the overflow module, it skimms just as effeciently as similarly rated euroreef and etss skimmers that i have seen in operation. the pred. 1 is rated for up to 150 gallons, if you want to spend more you can spend up to about 530 to get a dual stage deal that will do up to 500 callons and runs on about 1100 gph pump.
do a search for marine life aquatics and predator to find some places that stock them.
i run the aggressor, which is in my opinion, the best skimmer out there at 100 bucks, similar design to a berlin turbo, but more effecient, and a heck of a lot cheaper. my tank size didnt necessitate the predator, or i would have jumped on it after seeing 3 or 4 setups running them.
if you already bought a euroreef however, good choice, it will perform outstanding for you i am sure.
