    Does not work
  

*by L***Z on Reviewed in the United States on May 8, 2021*

I order this as it was described to be the Green To Clear (GTC). I have used the actual green to clear before and worked great. I bought it from a local pool supply store, how ever this product did not work at all a complete waste of money. On top of that the seller charged a 28.+ restocking fee the actual cost of the product.

### ⭐⭐⭐⭐⭐ 







  
  
    Great product at an amazing price!
  

*by E***. on Reviewed in the United States on March 21, 2020*

We usually get the 2# containers, but couldn’t beat the price on 4#.Learning curve- the container is much bigger (obviously) and one handed holding is not an option unless A- you have really big hands or B- your intent was to allow it to slip from you grasp and have the entire container empty into the pool in that exact spot. :)

    Wish I knew about this before! Great product!
  

*by A***R on Reviewed in the United States on September 24, 2020*

This stuff works. Always know when opening pool there will be some algae. Algae was there but after following directions, the water was clear in just 24 hours. So impressed and will definitely use again!
