These specially made air stone creates an abundant cascade of small to tiny bubbles rather than a limited number of larger bubbles. These smaller bubbles will be much more effective at moving water through the filter, making the filter more effective and efficient.

I ordered these not even considering the size of the tower tube they go down through on the under gravel system in my 60 gals. freshwater fish tank. They are quite a lot larger in circumference and where you attach the airline to the stones is larger but pay attention to the original stones have a rubber tube take it off the old stone and slide onto the larger ones and problem solved and they do create some bubbles works very well. I will see if any difference is made in the conditions of the water but always can turn down if need be.

Good price. I used it to give air to my plants in my self-built hyrodponic system. So far, it is working really well. My plants are thriving.

Works well in the hydroponic system. Evenly distributes bubbles to prevent the roots from rotting. All of them arrived in good shape and worked. I have been using them for a couple months and have not had any issues.

These stones put out a nice stream of bubbles that my beta loves. He uses it as an amusement park ride. I do have to tie off the air tube to decrease the air flow, because my tiny pump is really powerful.

I soaked these for 10 minutes and tested them all. They all met my expectations, nice and bubbly, lots of bubbles, the bubbles come out of the tip, but not the millimeter or 2 around the tip, but overall they all worked fine. Great deal.
