Aquarium Co-Op Weighted Air Stone

These work great. Their size is adjustable and they have weight to them!

Good purchase, i do water changes twice a week, and use this air stone to age the water. Other air stones will float half way or at the top, but the Aquarium Coop weighted air stone sinks all the way to the bottom, which creates better water circulation.

Outstanding

I put them on 2 of the largest non Coop sponge filters. They greatly improved my air bubble flow. I will be buying a few more in the near future.

Works great.

They are louder then other air stones since the bubbles can’t be smaller it’s still a good product

Great product. The weight keeps it down in the aquarium. I like that you can extend the length of the stone or shorten it to what you need at that time. This is the best air stone I have used by far. Thank you Cory

Good weighted air stone. Stays on bottom by itself. Gives nice stream of bubbles. Good price.

This is a great air stone!…for the lack of better words. I really like the weighted air stone, and it’s a product I didn’t know I needed, until the ACO took an existing product and made it even better.
