Air Stone for Aquariums,60mm Fish Tank Nano Bubble Stone Oxygen Diffuser with Suction Cups, Check Valve and Air Control Valve for Aquariums Ultra-Quiet and Easy to Clean

The media could not be loaded.  First this is larger than I expected and in my 5.5 gallon tank it's huge. Still I kept it because it looks like a Alka seltzer fizzing and the bubbles are soooo small.My air pump is from Walmart and I would probably suggest a variable pump but for now it works amazing.For the large one I'd suggest the smaller one but if you like my video get this one. So much cleaner looking than my air bar.
