Nowadays most skimmers use a pump and it draws air in creating airbubbles. THe depris in the water attachs to the air bubbles which like stated is pushed up to a collection and either collects there or follows a tube to a collection bucket. No how much you should pay for one is up to the user. But remember the expensive ones give better results. They can run any were between $100-$3500 and even more probaly. Now were they go, there are your hag on the back types that arent that good. They hang right on the back of the main tank. Then you have ones that will go right in the sump tank and skims the water there. And Last the nice skimmers that are to tall to fit in either tank and will be placed next to the display tank or anywhere the user decides and water is pumped from the tank to the skimmer itself. THese models I havent really seen in home aquaruims but all LFS will be useing these to skims most of there salty tanks.
