Biocool Clean My Water Tank Tablets are powered by OxyTech active oxygen technology – developed for advanced fresh water system hygiene. Unlike traditional chlorine-based sterilising treatments, OxyTech works by breaking down biofilm and organic build-up throughout the entire tank and hose system. Biofilm is often the hidden cause of unpleasant taste, odour and system contamination during storage. By targeting build-up at its source, Biocool helps maintain clean storage conditions without chlorine or harsh disinfectants. Application is simple: Add tablets, fill with water, leave for 12 hours, then drain. This pack of 50 tablets is sufficient for cleaning up to 200-litre water tank Ideal for motorhomes, caravans and boats – especially before the season starts or after extended storage.
