Sani Marc Summer Smiles 29-07216-90 900g Spa Broma™ Sanitizer is a practical and easy-to-use sanitizer for spa water. It dissolves quickly and completely to provide effective bromine disinfection, 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.
