### ⭐⭐⭐ 







  
  
    Bubbler for small tank
  

*by O***A on Reviewed in the United States on March 31, 2016*

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....

### ⭐⭐⭐⭐⭐ 







  
  
    Fish are happy
  

*by D***C on Reviewed in the United States on March 8, 2016*

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.

### ⭐⭐⭐⭐⭐ 







  
  
    Aeration Station!
  

*by M***E on Reviewed in the United States on October 18, 2015*

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