Sani Marc Summer Smiles 29-07055-15 1.5kg Spa Broma Ultra™ Sanitizer is an easy-to-use spa sanitizer that comes in tablet format to simplify dosing. The brominating tablets efficiently sanitize and disinfect water while also eliminating organic waste such as perspiration, body oils and cosmetics which tend to cloud water. Its odourless bromine formula works well in hot water, making it ideal for use in spas. It’s also gentler to eyes and skin than chlorine-based sanitizers. A great option for people with allergies or sensitive skin.
