I got the Y100 and it’s fantastic. Looks great in the tank and produces a very fine mist of bubbles. Great value for money.

Nice size it hides quite well in the tank and the bubbles are quiet and small or just what you want very pleased

The media could not be loaded. Surprisingly good. It comes with a valve that helps you control the amount of air going through which allows you to regulate bubbles.My only complaint is that the tubing it comes with leaks bubbles no matter how tightly you push the tubing on.I found it quieter than other air stones and the bubbles are very small in size which is what I wanted.

I like this diffuser, it looks great and the bubbles it produces are nice and small, and it's pretty quiet too. It comes with two suckers, and I thought great they will keep it straight and level, however, that was not the case. No matter how many times I try to fix the suckers to the glass, they will not stay attached which renders the diffuser unusable. I'll try to find some other suckers that will work, but really, I shouldn't have to. It's a nice product let down by poor quality suckers.

I bought this to replace an air stone that came with my original air pump, as the original was beginning to become quite noisy. After installing, its like night and day, the only noise now is from the bubbles popping on the surface. I have an inline adjustable valve to reduce or increase the flow rate, and it makes such a difference to noise levels. I was quite skeptical of the size, as it’s quite small, but on full flow, defo packs a punch when needed. Had no issues with the suckers included and it’s still in place.

After 6 weeks inly large bubbles come out, the fine mist bubbles armoneye gone. Not worth the .

Nice air stone 🌟👍

The media could not be loaded. Purchased this to replace the adjustable eheim one that came with my air pump that was extremely noisy and produced huge bubbles even when adjusted.It's only day 2 with it in the tank but so far it's really great, I chose the smallest option and have my air pump on the lowest setting and it produces masses of really small bubbles but what's most impressive is how quiet it is compared to my last one.As the previous one made large bubbles the noise it made when they popped on the surface of the water was very irritating at night when trying to sleep,This one produces very fine bubbles which are almost silent when coming to the surface,The bubbles are so fine that they float around the tank and almost look like glitter,If it becomes faulty or clogs up during use I will update my review & rating but so far it's definitely a 5 star item and I'm more than happy with it.
