My aquarium is about 40 gallons and my old air pump seems not to be very strong. It's an old Supra and I need to upgrade. Which pump seems to be the best for me? Btw, I'm new to maintaning a saltwater aquarium. I've had it for less than a year. Someone just gave me the old pump, but now I'm wanting a new more powerful one. Any ideas?
