HITOP6W Powerful Aquarium Air Pump, Dual Output 110 GPH Aquarium Air Pump, Adjustable Oxygen Aerator with Accessories for 20-150 Gallon Aquarium

My previous pump wasn't loud, but it vibrated on the floor with hard feet and made a lot of noise. THIS pump is quieter by default, AND the feet are a nice soft yet firm rubber that doesn't vibrate loudly on my hardwood floors. The air flow adjustment is wonderful, it's just a really great air pump. Remember to ALWAYS use check flow valves with ANY air pump!

I bought this to replace a very, very loud air pump, which made this very annoying & loud humming sound. This new pump is not only significantly smaller but it's also practically silent. Like my old pump, it's hooked up to two sponge filters, one in my 20g tank & the other in my 10g. Not only is it practically silent but it's also very powerful. An added feature I like is that it has a small orange light at the back by the dial that shows it's powered up. Can't comment on it's longevity YET as I've only had it running a month & a half but, so far I am very happy with it

This pump has been in operation for 8 months now, and I'm very pleased with it. Produces far more air than I can use for my 30 gallon, 2 air outputs, adjustable air flow, and oh so quiet! I don't even know it's on. Really! No vibration, good shocks and makes basically no noise. All you will hear is your bubbling water. When I bought this I compared it with four other pumps bought at the same time on Amazon, a Hygger, a Whisper, a Hiraliy, and a Persuper. Only one approached the quietness of this pump, the Persuper. The Persuper looked cooler and had electronic controls, but it was considerably more expensive and didn't have as precise a control over the air output. The Hygger advertised itself as the world's quietest pump, but I can assure you it isn't. Not terrible but definitely not as quiet as this one. The Hitop was the quietest pump and the best value by far. Personally I'm not crazy about how it looks, but that is just my preference. But I don't buy an air pump for its looks. And some others will probably love it. It works great, in any case. At the time of purchase it was $22.89 minus a small coupon savings.

Sets up in minutes. Just make sure you don't install in your tank. The unit stays outside the tank, and the attachments go inside. Also, measure how much tube you need before you cut.

Good power settings, long power cord, came with many useful airline accessories such as valves and connectors.
