### ⭐⭐⭐⭐⭐ 3+ months alge
*by T***E on November 12, 2025*

We've been using this for years now. 3+ months algae free inground pool. Water clear from opening in Spring to closing in the Fall on one dose.

### ⭐⭐⭐⭐⭐ Great Algaecide
*by B***K on February 14, 2024*

I’ve been using this for 15-years in my above ground pool. I use 1/2 bottle when I open the pool and 1/2 bottle when I close the pool. Hav not had one algae bloom in 15-years!

### ⭐⭐⭐⭐⭐ Seems to work
*by J***. on February 20, 2022*

Before and after pictures shows how the pool started and how it is 4-5 days later. I poured the algaecide in as product suggested. Chewed up my chlorine so I needed to balance it out with chemicals ph, chlorine, and alkalinity. Took a sample to pool store to test phosphorus levels and calcium. Once all was good. I added pool clarification solution. Seems to all have done the trick and seems to have really helped. Product is worth a try if your pool is green.
