### ⭐⭐⭐⭐⭐ Algicide for mustard mold in the pool.
*by R***R on August 20, 2025*

Got rid of mustard looking mold in less than a week. Great product and easy to use to control algae in the pool and spa.

### ⭐⭐⭐⭐⭐ Vegas Summer algae
*by E***Y on July 29, 2025*

Had an early Summer algae issue due to wind and leaves in Vegas. Dumped one entire bottle in and ran a cycle. Thoroughly brushed and vacuumed the pool. Had some foam when the waterfalls ran for maybe 10 days but not bad. The water is fine now. Upped my chlorine after also.
