what would you suggest for a filter for a 40 gl.Right now my choice is an ac500.I think this will defintily work but i just want some opinions from people.anything better than an ac that would do great on a 40?

an aqua clear 500 will be more than good.

You could also get a penguin 330. In my opinion, it is easier to maintain than the ac and the biowheel maintains the good bacteria in the tank through media changes (just a cartridge in penguin). You also have the option to use other filter media of your choice in a media basket. I use them both in different tanks and both have benefits. Penguin is a little louder because of the biowheel, and the ac promotes a stronger current. You really can't go wrong with either. Good luck!
