SeaKlear introduces WinterPill, a pre-measured slow-release chemical-delivery system for maintaining clean and balanced water during off season, to its AquaPill line. The company says WinterPill’s all-in-one formula helps maintain clear water, reduce scale buildup, prevent iron, copper and manganese stains, reduce unwanted non-living organics, control water rings, and enhance filter performance. The chemical blend is designed specifically for closing pools in winter; it floats under the winter cover distributing its four-part blend.
