I am also amazed at the capacity of this product in treating the water in the swimming pool. A bottle of this algaecide can treat a total of 25,000 gallons of water in the pool. This is a lot if you consider its affordability in terms of pricing.

There is also another advantage that caught my attention and that is the ability to be used in saltwater. Even though saltwater has a different chemical composition, this product still kills all types of algae in this type of pool water system.

However, there are minor issues that you must know before you consider this product. For this algaecide to be more effective, you must use it with chlorine to achieve the best result of the water treatment.

The pH level of your pool must also be in the proper range if you want to maximize the results of the treatment.
