Review on Pawfly 8-12 Inch Air Stone: Enhance Your Aquarium with Grey Bubble Stone Bar Bubbler Airstones by Crystal Harrison

Needs some work. Better would be a 2nd or 3rd way to hook up the tubing and mount it on a 1.5-2" stand with super suction cups. Maybe they'll make one. I don't know. Either that or a heavier base so they don't float and stay in place. I've tried putting it under the substrate but it keeps popping up. Glued to the bottom glass under the substrate with the suction cups I installed, but this reduced the bubbles coming out. They bubble up great, but you really need a way to put them where they stay just under a thin layer of substrate.One day I will find a better way to put them in an aquarium.
