About GLB

GLB Pool & Spa has been solving backyard water problems since 1956, when microbiologist Dr. Robert Stern founded the brand on a simple idea: pool care rooted in smart science, made easy enough for anyone to use. Nearly 70 years later, GLB is one of the industry's most trusted names in specialty pool chemicals — think Algimycin algaecides, the famous Super Blue clarifier, shocks, sanitizers, balancers, and cleaners that pool professionals have recommended for generations. GLB calls itself the gold standard in pool care, and the brand has the track record to back it up. Today GLB is part of the Solenis family (Innovative Water Care), a global leader in water treatment, following its years under Lonza and Sigura. For DIY pool owners, GLB means proven, professional-grade chemistry that takes the guesswork out of clear, comfortable water.
