Hello PT,
Sodium chlorite solutions are very effective both in cleaning up biofilm and keeping it from reforming. The range of applications runs from dental irrigation water, to greenhouse water, to heating systems, to cooling towers, to humidifiers, to piping, to emergency water storage, to "smelly washer" syndrome, etc. In many cases a shock dose of 25 - 50 PPM is sent through the system in order to break up the biofilm, then the concentration is dropped to 0.25 - 1.0 PPM depending upon the application. In some saltwater aquariums, the level is kept below 0.04 PPM because I believe some shrimp larva can be killed if the concentration exceeds that. In freshwater aquariums the concentration varies depending upon the species of fish, but is usually in the 1 - 3 PPM range. Also, ORP is used together with sodium chlorite solutions to keep the biofilm down in the tank. In general, chlorine dioxide penetrates the biofilm layer and changes to chlorite. As the bacteria grows, the chlorite is transformed back to chlorine dioxide and that kills off the bacteria. This goes on until the biofilm has been eliminated, then the reaction goes on to chloride and the chemical is washed out of the system. What is your application?

Would appreciate your insights, especially if you have had first hand experience. Thanks. PT
