I bought the 30 to have a slightly loose head to get some flow in my tank and it turned out perfect for mine 40 gallons out. . As it's noisy I have to say no, unless your tank creates a little waterfall with your filter, I'd say it will probably make a bit of noise, but if you're looking for absolutely zero noise pollution, don't do it it. . Actually put something in your aquarium. It comes with a hanging clip as well as a suction cup which is a good option. It produces tons of bubbles or none at all depending on your setting, which is done through an external knob located outside of your tank for easy access. If you have small fish that can be sucked into the inlet, suggest a top filter.
