Good 40% algaecide with no copper

Used this product for years. Works well.

This product works better than any I have used in the past

Great product for an even better price!

Works great to help keep algae under control

Great product that is reasonably priced

Effective algaecide, but foams. Good for pools without attached spa, waterfalls, or spray features. Otherwise, be prepared for lots of foamy bubbles.

I have tried different algae control products, but this one is the real deal, it really destroyed the algae other products were not able to.

We fought yellow algae in our pool for a couple months. Then we tried this product and it's gone with the first use and has been gone for over a month. Highly recommend.

Worked great for pool..cleared the water
