Review on EcoPlus HGC728450 Eco Air1 Commercial Air Pump 1 - 18 Watt Single Outlet for Aquariums, Fish Tanks, Fountains, Ponds & Hydroponics – High Flow, Silver by Richard Cheng

high consumption, low power consumption. The pump body got a little warm, so I added a 80mm main fan, now it hardly gets hot. now it's almost silent. No real complaints other than it has to come with an intake silencer and a fan, the only downsides I think it has. Also, do NOT run the pump 100% open, it likes a little back pressure at the outlet. Side . (You'll hear it settle down when you close the valves a little, and howl, vibrate when it's fully open.) This is because the pump's diaphragm is being recycled and colliding with itself. Imagine a flag in a hurricane flapping and flapping! Now you see! :)
