Marina Air Stone Extendable Range
The Air Fizz air stone range adds vital oxygen to your water through movement when the bubbles break the surface of your tank. Fish also love the currents created and many owners report the enjoyment fish get by swimming through the bubbles.
From time of order to installation in new tank, 3 days. Very happy! I connected 3 of these together (a simple task by following easy instructions) and installed in the new tank. These work awesome as a "BUBBLE WALL", the best I have had. I was really impressed with what I consider the low cost of the airstones and the effect that I ended up with. BIG BONUS: free and fast shipping. Thanks guys
