### ⭐⭐⭐⭐⭐ This CuLator 4.0 lowered the copper in my vinyl pool by 75% in 5 days to avoid staining.
*by J***3 on November 2, 2025*

I used a lot of Black Algaecide this summer, and the copper got very high - 90% too high. Just in time to avoid staining the vinyl liner this CuLator 4.0 lowered the copper in my vinyl pool by 75% in 5 days constant use in the skimmer. I dried it out in the sun for a couple weeks, put it back in the skimmer after rebalancing all my pool chemicals, and it lowered the copper another 5%, getting me to an acceptably low amount of copper so that my vinyl liner would not stain as easily.
