Review on 🐠 Aquarium Air Stone Bar: Silent and Subtle 6 Inch Fish Tank Air Diffuser with Control Valve - Ideal for Guppy, Shrimp, Exotic Species! by Kristen Wheeler

This product makes beautiful bubbles. I hooked two of these up to a 100 gallon Tetra Whisperer and in the 6 months I've had it I've had no issues with uneven bubble release. You can also get bigger bubbles by digging the stick deeper into the gravel, this gives you endless possibilities for the visuals you can create in your tank. I haven't read the description but they are a bit short (I have 75 gallons) but they still work great, improving the look of my tank and oxygenating the water. I highly recommend.
