Pool clarifiers are an essential product for maintaining the cleanliness and clarity of swimming pool water. These products work by coagulating small particles and debris, allowing them to be easily filtered out of the pool. They are particularly useful for removing microscopic particles that are too small to be filtered by the pool's standard filtration system. Pool clarifiers come in liquid or tablet form and are easy to use. They are a must-have for anyone who wants to keep their pool water crystal clear and inviting for swimmers.
