These are air stone beasts. They are big solid & heavy and pretty sturdy and they are so much more than I expected. The visuals in the water diffusion is amazing to see and they are ideal for aquariums with fish or live plants/both, and it is also ideal for hydroponics to and there are no problems with them floating off, they stay in place. We are very happy with them and they are excellent quality and I expect them to last a long time as solid and heavy as they are. Happy we found them! *If this review helped you make an informed choice about this product please take a moment to let me know that it is Helpful. Thanks!* ... show more

I let this soak for 2 days in a quart container with luke-warm water. It's making tons on tiny bubbles. This is the MED size and is very beefy. Nice and heavy, dont even need a suction cup. Works great! Highly recommeded.
