Hang In/Hang On Tank counter current protein skimmers were the first type of skimmers to appear in the saltwater aquarium hobby. They were simple devices which used an air pump driven air stone, the bubbles from which collected proteins and deposited them in a collection cup. These skimmers are the least expensive and the easiest to install and operate. With in-tank skimmers, there are no worries about wet floors.
