## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Excellent for clarifying winter swimming pools.
  

*by R***6 on Reviewed in the United Kingdom on 13 January 2024*

I have to say I was a little sceptical,  but followed the instructions with a chlorine shock, the added the fluid as per the instructions and now we have a crystal clear pool for the winter.  Only used a third of it. Made it really easy to get the leaves off the bottom. Ran the pumps for about three 2hr sessions to get it right and not had to touch it for over a month so far.
