EcoPlus 728450 Eco Air1 Air Pump 1-18 Watt Single Outlet, 6 Valve Manifold For Aquarium, Fish Tank, Fountain, Pond & Hydroponics, Commercial 793 GPH, Silver

I am currently testing this pump for durability. I connected the unit to a meter and in reality this unit consumes 30 watts not 18 watts as stated in the banner. I rechecked this using the Amp and Volts stated, and sure enough all the Ecoplus air pumps wattage are understated in the Amazon adverts, so beware. Model 728450 is 30 watts, model 728455 is 50.4 watts, model 728457 is 121 watts, model 728459 is 360 watts. So calculate your electric costs based on current and voltage, not using the wattage on the advertisement. Rather deceptive.

Like some other reviews have commented, this air pump has a slight machine odor to it - but not enough to bother me. I imagine it would go away after a few days.The build quality of this pump is generally pretty good although I think the precision of the cutouts for the rubber pads could be a bit improved. While I didn't have any problems with the manifold, I did have to make sure I was careful with it. The air delivery is strong.The air pump however, is quite loud on it's own but more importantly, the vibrations are very harsh with no way to tone it down. You'll definitely want to use this in a fish-room type of environment where you can spare the extra vibration. In a living room, or an office, it's too much.

The air pump is VERY VERY noisy, I have a lot of noise in my grow room and I can hear the air pump over everything else. Also as other reviewers stated this pump is NOT 18W they are lying and it will cost way more electricity than advertised. I bought this air pump solely based on the wattage as it was the same LPH than another manufacturer with less wattage, so I assumed it was more energy-efficient. THUMBS DOWN TO ECOPLUS

Excellent pump as far as noise level, if you have enough pressure. I love that you can link more than one together for better compression, but it shakes my house.Will NOT run 6 - 4” round flat airs tones, even with only 5 air stones if the stone is deeper than 1’ foot, it doesn’t bubble.Good value, know what you are buying. I suggest 6-2” air stones for a single pump.

I have a RDWC system I built with 6 tubs and was using two popular brands of aquarium/hydroponic pumps and still not getting the flow this one pump has. It is thunderin loud if it was used in a living room aquarium setting but that isn't what I am using mine for. Very powerful and all six 4 inch disk air stones are bubbling away beautifully. Thanks.
