CuLator

CuLator takes a genuinely different approach to metal stains in pools and spas. Developed by Periodic Products, Inc. — a Florida material-science company founded in 2009 by chemist Dr. Joseph Laurino — CuLator uses patented Chelok polymer technology to physically remove stain-causing metals like copper, iron, manganese, cobalt, and lead from your water. Unlike sequestering agents that only hold metals in suspension (and release them again as they break down), the CuLator PowerPak sits in your skimmer or pump basket and permanently traps metals inside the bag, so you simply throw them away. Nothing is added to your water, making it a natural fit for fresh and saltwater pools alike. Made in the USA and backed by a portfolio of U.S. and international patents, CuLator is the smart, chemical-free way to stop green water, rust stains, and discoloration at the source.
