hygger Aquarium Air Stone, Aquarium Bubbles Air Stone, Fish Tank Bubbler Ultra Silent Deep Dissolving Oxygen Diffuser Kit for Air Pump Fish Tank Small Bucket and Hydroponics(L)

I bought 2 of the larger ones for my 120 ltr tank and they are perfect. I am running a twin air pump 9 watt and the output is excellent. The noise level is minimal which was a major factor having tried a number of other ‘bubble’ bars. The size of the bubbles are very small in comparison to other bars which is more an akin to the fish having a jacuzzi rather than a previous bubbling cauldron. FINALLY, I have found the solution. Thankyou.

Absolute rubbish. The glue on either end comes apart and all you get is big globs of air bubbles like any cheap stoneBoth my friend and I had the same problem.

I like the air bubbles their are smaller than others

Great Air stone .. no float.. super fine bubbles exactly what I was looking for

This is so loud

Fish love it. Bought a few months ago and still working well.

The unit feels nice quality, when you start using it it's ultra silent and lovely tiny bubbles.A day later the annoying chirping sounds start.After a week it's a mix of high pitched screeching and chirping at all power levels on my Hygger 10w silent air pump(which is super silent by the way)I've also bought the Hygger air stones from the US site and it's the same story.Hoping at some stage someone can solve the chirping and screeching sounds. It's unbearable..

Very easy to install, a little larger than I expected, but lovely soft bubbles. Once installed did not take long for full curtain. One of the fish likes to lay across the bubbles but not for long. Really good buy.
