### ⭐⭐⭐⭐⭐ One and done!
*by A***R on October 12, 2025*

This little thing packs a huge punch! We just drop it in and it helps greatly with keeping the chemicals in our pool balanced. It helps control the algae in the pool. It's well worth it's cost. You'd be spending much more on chemicals and wasting so much time!
