I’ve used this air stone in my 10-gallon tank for three months. The bubbles are consistent and the water seems clearer. It fits nicely in the filter and doesn’t clog easily. My fish are more active and seem healthier.

Works well with my existing air pump. The bubbles are fine and spread evenly. I noticed better water movement after installing it. A little noisy at first, but it settles down.

Great for a small tank. Easy to install and fits perfectly in the corner of my aquarium. My betta fish swims more freely now. No issues with durability after two months of use.
