ChloroKlean Plus L20 is an advanced water treatment solution designed for hot tubs, spas, swim spas and swimming pools. Combining chlorine dioxide generating technology with sodium hypochlorite chemistry, it provides powerful oxidising action to support water hygiene, system cleanliness and biofilm management.
Developed for use as a pre drain down system treatment, ChloroKlean Plus L20 helps clean internal pipework and circulation systems prior to water replacement. The advanced liquid formulation distributes rapidly throughout the system, helping reduce the build-up of organic contamination that can accumulate within plumbing and hidden circulation lines.
Unlike traditional tablet-based treatments, the liquid formulation is easy to measure and dose, with no crushing, dissolving or pre-mixing required.
Each bottle contains 25 x 40ml doses, making it suitable for routine maintenance programmes across a wide range of hot tubs, spas and hydrotherapy systems.
