    Looks good!
  

*by L***Z on Reviewed in Canada on 11 June 2022*

The product seems good & intact intacted. However, it does not look like the bottle in the picture. It is a white bottle but I can not wait to see how it helps with my seven glowfish tetras!

### ⭐⭐⭐⭐⭐ 







  
  
    Water is well balanced
  

*by A***M on Reviewed in the United States on 22 October 2024*

I use this between maintenance cleaning and it helps keep my water balanced. The water gets cloudy for about 24 hours after putting it in, and it goes in gloppy, but everything is balanced and it works.
