## Customer Reviews

### ⭐⭐⭐⭐ 







  
  
    Perhaps a little noisy
  

*by C***R on Reviewed in the United Kingdom on 22 August 2022*

Have now been using the first air stone for around two weeks. Works fine however I think they are a little noisy compared with the Bi-Orb originals. Maybe it's because the bubbles are a bit larger. Don't know if that will affect the function of the filter - only time will tell. The extra noise may be an issue if the tank is situated in a bedroom.
