This is THE BEST ever! You won't go wrong with this!
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.

Makes your green pool blue
Pretty great at keeping my pool clean. Just like th stuff you find at the big box store. I've never been obsessive with the chemicals in the pool, just finding a least minimum amount of checmicals to keep the water clear and the water not being too imbalanced. When things get out of hand or there was a large storm this is great for getting things back on track.
