Review on 🐠 Enhance Oxygenation in Your Aquarium with uxcell Mineral Fish Tank Aquarium Bubble Air Stone Oxygen Airstone Bar - Vibrant 3PCS Colorful Set by Natalie Martin

These little things that go together are great. Don't buy the big round 2-2/12" those are junk. They don't bolt together, they snap and just fly apart when you apply air to them creating a huge air leak. With the same success you can just pop the hose into the tank with nothing on the end.Update just bought another set these are small they are great and the shipping was ridiculously fast!Also I found a use for my old clogged air stone.
