- 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.

Order on Wednesday received on Thursday works great
It’s obvious that these weighted air stones are not your average air stone. Been running over a week now and I’m very pleased with them. Nice bubble size, great flow and love the option for modularity by stacking them.
Another home run for the Aquarium Coop design team.
I always but a line of air in my tanks, nine to be exact. I would fight with rocks or something to keep the air stone down. I love these air stones. All I have to do is connect it to the tubing and drop it in the tank. Man I just "love" these air stones.
Super nice to have that weight to pull the air stone down to the bottom of the tank. I was having issues with my air stones floating to the top of the tank when I wanted a little extra air, and this fixed that issue. Also seems like the bubbles are a little less fine than the ziss air stones, but it also seems like that'll get rid of any clogging whatsoever. I will be shocked if this airdrome ever clogs to be honest.
Stays down where I put it doesn’t float up like the others I like them I only got one pack need to get a couple more. Thanks for another great product.
