This is everything you need with the exception of your gravel and plants! The filter actually sends air bubbles down into the water, thereby, aerating the water without the necessity of a separate pump and air stone to do this. The lid fits the top of the aquarium perfectly. Also in the back of the lid are two removable pieces (which you can reinstall later if needed), so you don't have to break off pieces of plastic to make room for your filter. I really like this feature. I am extremely pleased with my purchase and would definitely recommend it to others.
