All Pond Solutions Nano Slimline Aquarium Quiet Air Pump, Black

Perfect for my 40L tank. Nice and quiet and great amount of bubbles. wasn't expecting it to be this good for its price. it comes with a lengthy amount of tubing and suggests to cut it to size in the manual for more power. I opted not to do this and am very glad as with the extra tube i have been able to wrap it behind the tank and among the plants inside to hide it from view whilst placing it in the perfect spot of the tank. So unless you have a huge tank I wouldn't even cut it unless you need to for space.

Its small, its able to stick onto the outside of the aquarium no problem. You get more than enough pipe line. Plug is slightly bigger than expected but all in all - good product!

Bought three of these. Very quiet to begin with, but after a few weeks all three got very noisy. Upsetting, because it's a good pump and worked perfectly and quietly for about a month, then a very loud humming occurs.

Not a silent one, noise level is pretty much low. Good for 5-10 gallon tank. It is small and handy, can be attached to glass with a suction cup provided. Good product.

My last pump made a racket, this is silent. Anybody else mentioning sound must have a airstone that's too big for the tank or something. The air stone that comes with this is your typical small one and the only sound comes from that as the water hits the top of the tank as you would imagine!The pump is amazing, literally no sound you can hear and I have the tank next to me in the living room. Really nice surprise as I was expecting even just a bit of vibration/noise but it's actually attached to the side of the tank and I can't hear it at all. Brilliant.

This is a very loud air pump, there is a constant vibrating noise that is really annoying, it’s powerful enough to use with a bubble wall or use with the air stone provided either way it’s still really noisy, to be honest I really wouldn’t recommend this it maybe small and look nice but that’s about it I’m afraid

As an air pump it works and it is small but my god it is NOT quiet!! It’s not even that it vibrates against a surface it’s the internal mechanism that sounds like a herd of elephants playing the drums, I haven’t heard that much noise out of something so small since my newborn son had colic.If your aquarium is in the garage or the garden shed or if you like to spend time watching your fish and wear a hearing aid you can turn off then this product will be fine, otherwise another product will be better, I will be ordering a new one.

Looks lovely in my fish tank, not very noisy at all which is exactly what I wanted. I placed the stone under a stone so it’s hidden and the air bubbles cascade up and over them. Looks a great addition in my tank. Delivered on time and will use again for any other things I need for my tank as the price and quality were fantastic.
