euroreef recirculating skimmer vs regular euroreef skimmer

[greenmaji]

....i remember reading somewhere that the needle impeller (which is the key part of these skimmers) is only available by itself to registered owners. so if it ever broke on me after having bought it used i'd be up the creek without a paddle....

Sendra pumps needle wheel impellers are sold separately.. Just a link I stumbled by, by no means the best deal..
