I have it hooked up to a gold fish tank outside, running a big sponge filter and air stone. Been running through Temps from about 15- 30 + degrees so far I'm happy with it
I use it for my Smokai generator I’ve had it for over 10years!! and just had to replace it for a new pump now, couldn’t ask for better than that, great pump for a great price
This air pump is not the quietest, my USB cheapy and ehiem are definitely quieter, however for price point it is great and there are things you can do to dampen the noise eg sit it on a thick cloth and make sure it isn't touching anything. We have it in our lounge near where we watch TV and it isn't noticeable. It is also really powerful, more powerful than my other two I think. Very happy, it's doing what I need it to 😊.
I was so impressed with this pump running 6 x 62 litre tanks with 14 attached air using filters and stones, and being almost completly silent, that I ordered another for my goldfish pond, 500litres.
All good thank you highly recommend
