4 Inch Air Stone Disc Bubble Diffuser for Aquarium Fish Tank Pump Hydroponics

This air stone does the job in my 65 gallon community tank. It replaced a bigger stone of a different branding that went past its shelf life and I thought it might be a bit undersized, but I have to say that it works well and puts out a large amount of bubbles.Entirely adequate, good looking and priced right. Can recommend.

Hard to see in photo but it works great it produces very fine bubbles and I feel more than comfortable with it being paired with stream waterfall doing all the Aeration in about a 500 gallons pond. At first it seemed like it wasn’t working right because bubbles were coming out of the side of the stone not the middle but what I had to do was have the barb for the air hose facing up and allow all the air out of the stone while in the water and connect my air hose while doing this and it fixed my issue and works great. And the weight of it is more than enough to keep in one place. Overall great product. Time will tell but I would buy again.

Works great

The media could not be loaded.  Easy to install. Nice addition to any fish tank.

Well packed. Received overnight. Outstanding service. Well worth the money.

A little bit more expensive compared with other air stone but this one look nice and it is really heavy so no way anything on the tank can move it.

Awesome addition to 75 gallon tank

I bought this expecting yo use the same line that I use for my bubble stones…could not make it fit. Probably on me for assuming….
