2nd purchase very trusted product, used in several different set ups, first one has been running w no issues for almost a year, LOVE the high and low setting switch. Great volume and very low noise

The media could not be loaded. Edit January 22, 2025.This air pump continues to impress me. It is so quiet. It doesn't appear to be over-worked. It never gets warm to the touch. It is POWERFUL! My two huge bio filters are running at max efficiency. In fact, I had to turn the inline control valves way down, as there was just too much air flow! I have never had that problem before!I have updated my pics. Look at that crystal clear water! Couldn't do it without an adequate air supply.I bought this air pump for my new 75 gallon aquarium.I am using it to run two HUGE sponge filters.I have the pump sitting above and to the right of the tank.This pump is so powerful that I had to use two air flow control valves to turn down the flow!Not only is this a strong pump, it is very quiet.I am 110% satisfied with this pump. I'd buy it again.

I bought this after returning a very noisy linear piston pump. This one is as quiet as they claim, and puts out a fair amount of air. I have 4 large air stones coming off this.. they work fine but using 3 air stones is way better for hydro purposes... just a lot more violent bubbling action. I may buy another.

High output air pump and very quiet . Well made. It can support a 6 port manifold. Very happy with my purchase of 2 pumps.

This is a pretty cool pump. It is pretty powerful for it’s and you can run at least 3 small to medium size tanks with it. The only reason I didn’t give it 5 stars is because it is a little nosey not super noises but it does have a little hum to it. I think this pump would definitely be a way better choice for a fish store or a business like a dentist office where there is existing noise in the area to cover the sound of the pump, but definitely good pump just not for a living room or somewhere quite.

Should have bought this awhile ago.Quiet but puts out a lot of air.

This air pump is way better than the other brand I've used for 4 yrs hands down. It's actually quiet as ever which is really nice. Handles all 4 towers on my undergravel system which is a Lee's premium. I like the metal closing valves more so than the plastic ones of before. A very simple, easy set up which was very glad I purchased this.

OK, first off…. This pump worked great! Had awesome airflow, two settings for high flow or low flow, a nice set up for managing the air with four valves that I could use to send vary out of air to different things… and best of all, it was QUIET! Barely the slightest hum and you could only hear that if you were standing right next to it! It sits on the bottom of my aquarium stand less than 8 feet from my recliner and I can’t even hear it over the bubbles it makes. So all of that stuff is great! I was totally thrilled and completely happy with this for about 8 months…. Then I noticed that the amount of air going into my aquarium tank had begun to drop off…. I went and pulled out my manual and as a suggested… I cleaned the air intake and open the housing to check that the bladder was OK and everything… It all looked good and the airflow did make a minor improvement but it’s nothing like it was at the beginning. I don’t know if maybe it is just starting to wear out but I did expect a longer lifespan than eight months… Highly highly highly suggest buying the two year warranty and replacement plan for this product so that if this happens to you, it’ll get replaced. I will be buying another one of these pumps, and this time I’m putting the replacement plan on it!
