Same great performance as the standard EcoSystem - but with the addition of a Bak-Pak Protein Skimmer to adsorb and entrap wastes. Includes everything you need to get started - even the lighting. Convenient, hang-on style requires no under-tank cabinet space and no additional plumbing. Grow beneficial macroalgae and microorganisms for improved water quality and to feed your aquarium fish and invertebrates the way nature intended. Fits all glass and most acrylic aquariums. Requires 5" between back of aquarium and wall.
