hygger Adjustable 5W 10W Aquarium Air Pump with 2 Ports for 20-600 Gallon Fish Tank 160 GPH 250 GPH Aquatic Aerator Oxygen Pump

So far so good with this unit. It has excellent power and has been running for over 3 years with no issues. It also is very quiet.

NO hum CAN BE accomplished. Extremely low hum sound especially compared to my other air pump and returning model advertised as low noise (both air outlets must be used to be quiet). I totally reduced the extremely low hum to NO hum by placing the box included packaging foamy material under the air pump and placing about 3lb (1.4kg) weight on top of the unit; this got rid of any left over vibrations. I am checking for any heat where the foamy material touches the bottom of the air pump but none so far; I am very careful of the added foamy material because heat can reduce the life of the unit. The unit is sitting on the floor as shown in photo and will go under the furniture out of sight.The air flow is great as can be seen from one of the photos running at maximum into the 9 gal (34 liter) tank; in reality I see more air bubbles than the photo. The air control can easily keep the air flow at 0% to 100% and anywhere in between very easily; my other existing and another air pump I am returning are much harder in control. I am keeping the air flow at around half or less.There are two air outlets but if you only are going to use one, then either connect both into one with a T or Y valve connector, or block one of them. I am not sure if blocking one of them damages the unit so I have two output air pipes connected by a T valve connector into one pipe. Not using both output air outlets causes this unit to be as noisy as the competitors quiet air pumps like the one I am returning.In conclusion the price is a little high but for someone who can't stand the air pump hum, THIS IS AMAZING :-) I can actually sit on the couch look out the window and the fish tank and relax without any hum!!!The packaging of the unit is higher quality along the lines of quality computer products In comparison tosome of the other aquarium accessories. I guessing my unit quality is the same quality as all the other shipped units.I hope you found this helpful.

The media could not be loaded. This pump is extremely quiet, it more quiet than my top fin pro 110 hang on back filter, which is impressive. It has two slots for you to hook a hose too and is adjustable to the specific needs of your fish, too much oxygen no problem just turn it down, too little turn it up, works great with my Hygger 15.9" bubbler. I dont have another bubbler just the one for my 55 gallon for my african cichlids. You want this thing super quiet hook a second hose to it that ur not using and it will be 10x more quiet. I have a video with a second hose on it, as u can hear cant hardly hear it at all, but when the second hose was off u could hear it 10x better.

Super quiet! The bubbles it generates are 10 times louder than the air compressor itself. Had it for a few months now and is going strong running 24/7.

Just purchased this Hygger HG-981-10W adjustable air pump , fits perfectly in lower sump pump cabinet, but most of all impressively quite quiet, comparing it to my previous Tetra Whisper AP300 air pump which had one of two air outlets give way, as pictured I had purchased a repair parts kit which by the way had clear instructions and I had previously been successful in getting air flow back with the replacement parts, but this time the pump did not work after replacing. This was my second pump from Tetra in as many years and finally frustrated and decided to give Hygger a try as other Hygger products I’ve purchased in the past have not given me any issues, I was rewarded with a quiet, foot friendly (size) and adjustable air flow I did not get from the Tetra Whisper AP300 which works quite well, this has been a perfect alternative, albeit it’s longevity, which I will update in the future on its progress! I hope this pump lasts long enough to surpass my last one, so far it’s neck and neck out the box, longevity will prove the winner here, for now I will recommend, size, features, 2 outlets adjustable air flow, quiet, and priced lower than the Whisper AP300

I did have a problem with the first one. I ordered, but I contacted or should I say they actually contacted me. Because of my recent post and bam, they sent me one that works perfect. It's super quiet and it works unbelievably great. I would totally recommend getting this. If you have any size aquarium or if you need a pump with 2 outlets, this thing kicks well, you know.

I am honestly amazed. I’ve had aquariums for the past 30 years, and I’ve never had an air pump run so quiet. Hopefully it stays this way!
