Lots of bubbles from these stones.. I had multiple in a couple of my tanks because they didn't release enough oxygen for my fish … I only need one of these ! Even in my larger tanks one of these it all THATS needed . Nice big size too ! They sink to the bottom like they're supposed to . This is my first time using them and I'm hoping they last a long time ! Im going to order more to have on hand ! I highly recommend them !

“My Goldies”

Well made, aerating my 60 Goldfish pond wonderfully…using a single double air pump for constant air flow bubbles- for maximum oxygen distribution in my above ground 600 gal water tank…also using a cascading waterfall pump

The product is great...larger than the stone balls that came with my aerator! Good price, good bubbles and no noise. The only problem I had was I order them because it said next day delivery, but delivery was delayed several days. Fortunately I only needed them to replace one stone.
