About Us

BioLab Inc was established in the USA in 1955, beginning as a small family business. Initially it made cleaning agents and disinfectants for the poultry industry but Founder/CEO Leon Bloom, soon realised the products could be used for other industries.

As early as 1962, Atlanta-based BioLab Inc had expanded and the BioGuard brand of pool and spa maintenance chemicals was created.

By Exploring microbiology and chemical processes, BioLab Inc also realised that the traditional one-cure-fits-all approach to swimming pool care wasn’t enough. Consumers wanted a program that made their pool chemicals work together, with the outcome of a sparkling pool. Thus, the three-step system was born, overcoming many traditional pool care problems.

Leon Bloom sold the company to Swedish chemical supplier Lonza Group in 19179 and retired to Florida shortly thereafter.

By 1980, the business had become the world’s leading manufacturer and marketer of pool and spa chemicals. In 1983, Alex Chandler of BioLab Canada, led the push into South Africa and Australia with the BioGuard brand. In 1993, the BioGuard brand expanded into New Zealand. In 1996, Great lakes Chemical Corporation purchase BioLab from Lonza Group.

In 2013, BioLab’s global business was purchased by KIK Consumer Products, one of North America’s largest independent manufacturers of consumer products. BioGuard pool and spa chemicals are sold in hundreds of stores across Australia and New Zealand, making us one of the largest retail networks in pool and spa chemicals in Australasia.
