boxtech Aquarium Air Stone, Nano Air Stone Aquarium Silent Diffuser for Dissolved Oxygen, Used in Aquariums and Hydroponic Pumps (Y100)

Great little air flow. No noise a lot of rapid bubbles. Very fine quick bubbles

Great product very happy

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.

Item produces a good flow of bubbles only down side is having to keep fixing it back to the tank the suction caps supplied are useless.

Works very very well, it is simple to install and gives very high oxydation to the tank. The item comes with 2 suction cups and they work really well and have both stuck in place, most aquarium keepers will be aware that some don't stay attached to the glass, but these both have. The nozzle fitting is for the standard tubing size and it also comes with a blue flow regulator to fit along the tubing. The weight is only a few grams, perhaps 10 to 15 so it is very light, this being said, the low weight does not detract from the quality of the build. I've included a video so you csn see it in action.

i have tried everything and it will not clean thegreen algue off rubbish

I have happier fish because of this product. I’ve noted some comments about suction pad issues but so far so good for me

Very happy with the product. It secured well to the tank, and being clear isn't a distraction. Having the control value helps to regulate the flow of air into the water.
