Sinddy 40mm Diameter Aquarium Fish Tank Ponds Ceramic Oxygen Air Stone Diffusers

I was going to say this makes great bubbles for a small tank (it's a 2-1/2 gallon tank). But realized it's no longer working, I have had it for two months, not sure of the life expectancy. It did make good bubbles and it didn't overpower my tank, but no more bubbles....

Bought this stone over a month ago and it's working great! I was worried it would be too overwhelming for my 6 gallon tank but immediately the fish started swimming through it and they seem much happier. Looks great and gives a nice stream of bubble.

Excellent stone. Nicely aerates my tank. About the size of a 50 cent piece.

40mm Diameter Air Stone works great!

We ordered 2 and only got one. Wasn't worth going to the trouble of trying to prove that and to get another one

As described. Good value.
