Pawfly Aquarium Air Stone Disc, 2 Inch Small Fish Tank Air Stone Kit Ultra-High Dissolved Bubbler Airstone with Accessories for Aquarium Fish Tank and Small Bucket(Pump Not Included)

This creates lots of bubbles and after a few months of use has not diminished in bubble volume or quality. I purchased it for a 20 gallon tank but I actually think it is too big for the tank and creates too much water movement with all the bubbles created. So I moved it into a larger tank.

I love it. The suction cups hold it in place nicely and has a lot of air bubbles. Very happy with purchase. I'd had a previous tube shape stone and this is much better. The long tube shape one would clog up easily. Haven't had any trouble with this purchase.

Tons of bubbles and fish love it!

Awesome bubbles

I bought this as my current air stone was not as powerful as I wanted it. I soaked it in water for 24 hours and it bubbles very nicely. I also upgraded to a more powerful 4-watt air pump since my old one would not suffice. I’ve had it for over a month and so far, no discoloration on the white part. I’d buy it again.

I didn’t realize how small it’d be but I’m actually glad it is, it works great
