4" Large Air Stone Cylinder
Bubble stones fired at high temperatures have uniform and delicate pores, which can be reused and have a long lifespan. The bubbles are delicate and not easy to block, with many and dense bubbles.
Suitable for use in freshwater environments, increasing the oxygen content in the water and creating a safe living environment for fish, such as aquariums and fish tanks.

Using all 4 pieces between two Hygger 610gph air pumps 10 watts and they are almost filled with bubbles more than 75% of the cylinders. Gonna buy more for my third air pump

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!*

These are great if you don’t put them too deep. They work best from 0-2 ft. Volume diminishes after that. I use these for my Koi tanks outside. I did have a couple of these airs tones that didn’t work very well from the start. I also have bought about 12 of these so far and over all I have had good luck with.

I use these to create bubbles for a brew that I make to put on my plants. I needed something a little stronger than the little ones I had so I purchased this pack and these create the right amount of bubbles. I need to keep my tea brewing for my plants :)

Need a really powerful pump to utilize. It has a hard time putting out because it’s so big. Air typically only comes out in 1/4 to 1/2 of the stone. Definitely soak it before use. I returned mine and went with smaller stones that put out more air.

The air stones arrived damaged. I guess these being bulky, they need more than the thin layer of bubble wrap they were sent into.The transport boxes were perforated at the point of their air connector.Out of 6 stones, 3 are broken, i will need to use epoxy to repair them, otherwise they will leak big time and be unuseable.The 3 others have small notches and shards broken off but the nozzle is useable.They look sturdy.They are 1 7/8 inch diameter and 5 15/16 inches long.They are for oxygenating a natural swimming pool on a 5 cfm air pump.Returned. Waiting for refund.
