    Stones received on time
  

*by D***R on Reviewed in the United States 🇺🇸 on May 25, 2021*

The stones work great providing lots of bubbles to my water-garden pond. The only issue is one of the stones needed to the stem to be hot-glued to the center.  Once I did that I had 2 beautifully working aeration stones at a good price!

    Love these more than the other types on amzon
  

*by B***R on Reviewed in the United States 🇺🇸 on February 23, 2021*

Love these stones wish I would of went with these instead of the big 4” round ones only because after I got those the add was miss leading so I had to buy more stones and went with these. For my 20w pump these would of been better flow I have to limit these down a little so the 4” round ones will let air thru them .

    In a comparison test, this seems to work great for DWC
  

*by G***3 on Reviewed in the United States 🇺🇸 on August 4, 2020*

I have tested this 4 inch cylindrical stone with two other styles. The other two styles stopped working effectively after less than one week. I have 8 of these stones running off of one 1110GPH pump and they still produce an ample supply of air with no noticeable decline in efficiency after three weeks. I am purchasing more to have on hand.
