The air stones work well in my 50-liter tank. They create a steady flow of bubbles that help keep the water oxygenated. Easy to install and the bubbles are gentle on the fish. I’ve used them for over three months and they still look new.

Good quality and affordable. The bubbles are consistent and the stones don’t clog easily. I paired them with a small air pump and noticed better water movement in the tank.

I bought this set for my betta fish tank. The bubbles are soft and the stones stay in place without falling apart. Works perfectly with my existing pump. Would recommend to anyone with a small aquarium.
