Review on AQUANEAT Aquarium Air Pump 300GPH: Powerful Hydroponic Aerator Pump for Up to 200 Gallon Fish Tank – Oxygen Bubbler Included! by Jenny Hupke

God this thing is loud and don't you dare block any of the ports because it looks like it will explode if you do. I was going to disable one of the ports with a linear regulator, but no thanks. It sounded like someone turned on five pairs of hair clippers and put them in a steel drum and when I tried to see if I could block one of them until I needed them later it was a mistake. It just increased the noise by 100%.
