Hey Figdish, They are a little noisy, but when adding more, and more equipment to a tank,.....it's noise that you've never experienced before. Once it settles down a bit, it'll quiet down. But it will help the tank. As long as there are no air bubbles in the intake pipe, and the pump is only pumping water. It should quiet down.(a bit). Did you try the light? Any better that your original?
