Review on 🐠 AquaMiracle Aquarium Powerhead Pump: 135 GPH Water Circulating Pump for 10-40 Gallon Aquariums with Aerating Benefits by Emily Morris

Seems a very good deal and easy to install. Plenty of water suction and circulation and ventilation. However after 2 days it seems to buzz louder than my old pump which unfortunately died. I have checked that it is not against the wall of the tank and that the suction cups are in place and providing some clearance. I've connected an air hose to it, but when I turn it off it still buzzes, so I'm not sure what to think yet. It's very reasonably priced although it's in our living room so the noise is noticeable.
