### ⭐⭐⭐⭐⭐ This is THE BEST ever! You won't go wrong with this!
*by S***D on December 23, 2025*

This is by far the best product for killing algae and it gives you the most amazingly clear water you have ever seen. I use it weekly and I wish I had known about this years ago when I was fighting algae and raising my chlorine level without ever using pool stabilizer (CYA) . They are not lying when that say it cures 90% of pool problems.
