VIVOSUN 634GPH Aquarium Air Pump Commercial Air Pump with Aluminum Housing | 6 Outlet 25W 25L/min, Fish Tank Bubbler Pond Aerator for Aquariums, Ponds, Hydroponics

I was very impressed with the quality of this 25 watt unit. I have an 11 x 16 water garden, and it pumps more than enough air...it would be way too much for inside aquariums. I only had it running for one day and it seems like the fish are a little more active. It's is fairly loud, but the pump is in a small water mill house, and you can't even hear it on the outside. I am very happy with my purchase

Works great. I like that it comes with an attachment with 8 ports so u can use 8 air hoses. I use it for making aerated compost tea brewing. It gets the job done.

It is an extremely good pump, moves air really well and is very compact. You're getting a lot of airflow for the money you're spending. However, the pump is insanely loud. I do NOT recommend buying this if you live in an apartment. I live in a townhouse and I had it in my garage originally, but I had to move it into the basement as I could hear the thing down the block.

Arrived on time and with no issues. This was purchased as a gift and they like the product and I uave saod it works great. I plan I getting myself one as well.

Extremely hot. Will burn you if you touch it. Quite loud. If you are running it inside a cabinet, you might be alright. In an open space, it would be too loud. I’ve been running it for 2 weeks. We’ll see how long it lasts. It does produce a significant amount of air.

Still running well, constantly, powers 28 air stones/foam filters. I bet I could add another 10 or more, easily. Thing is a beast, albeit a bit of a noisy one. I keep this in a separate room upstairs. Runs warm, not hot, IMO. Would buy again and probably will for a spare at least.

This being sold as a "industrial" air pump is misleading. I used several aquarium air pumps that ran for many years continuously with minimal noise. This one on the other hand is a piston based air pump vs the diaphragm air pump that would usually be used in am aquarium pump. Once the unit became so loud and performance dropped significantly. I took the unit apart to inspect the problem. The problem is in the core design itself, with the piston rings being made of eith nylon or Teflon. The cylender walls were heating up and causing the nylon rings to disintegrate the material was all over the inside of the pump in a black powder. Clearly this wasnt designed to last. I ran the pump for an aquaponics system for about two weeks before it was sounding like a garage air compressor. No exaggerating. Going back to a diaphragm.

Pump gives great air. But, it is very noisy. I can't use it inside my house.

Worked less than 10 mins

Ma première pompe a fait presque deux ans à fonctionné 24h sur 24 sans arrêt,je recommande cette pompe très silencieuse, pour la qualité et son prix abordable,je m,en suis commander une deuxième tellement elle est efficace!

Good air volume, a little noisy works great for me

Great pump. Works well,

For my air pump needs this thing is powerful. My biggest complaint is it is loud. I hang it off the BBQ to stop any vibrations but I wouldn't want it in my house at this level of noise. Works really well otherwise.
