An Airstone That Works All the Time
- Weighted to sink
- Modular height
- Easy to clean
Keep your aquarium well-oxygenated by using an air stone with your air pump. An air stone is used to diffuse the air into smaller bubbles that agitate the water surface and increase oxygen levels. We built our weighted air stones with little, modular discs that can be snapped together or removed to create the perfect size. Plus, its small diameter is perfect for fitting inside common air-driven devices, like sponge filters.

Customer Reviews
I had a scheduled power outage, so I purchased 4 air stones with the pumps and tubing. All of them worked very well and the air stones remained in place. I am happy to recommend them.
Exactly as advertised, they make having air stones easy to manage and hassle free by staying where you place them
Order came in a timely manner. Will shop with this company again.
These are the best I have ever used in the down tubes in my Undergravel filters. Smooth and even bubbles and easy to clean .
Perfect for small tanks
