I have a 55gal tank on the way and am wanting to put a bubble maker in so my future turtle will have some entertainment. Any suggestions on what pump? Also, would it be possible to put a fish in the tank with my turtle? And if so what kind of fish?
Any inexpensive air pump should do. The size of the pump usually depends on the depth of the tank and the number of air stones being driven. Just make sure to get a pump that can power a single stone in your tank.
