This aquarium has always been freshwater, so the skimmer has never been used. Recently the pump was replaced with their new upgraded model, so its powerful and quiet. Comes with the black stand and quite a bit of accessories; extra exterior pump, pail, net, all sorts of plant food and so much more.... This aquarium is 6 years old which reflects in the price. I am open to offers for those seriously interested. If you don't want the fish, that's okay I will take care of them; Large Pleco, 2 cat fish, 2 guppies, 4 dwarf algae eaters and a Tetra. Need more info, please refer to the Red Sea website.
