Polluted water systems are easy to ignore but the results are not. If you want to avoid a holiday blighted by sickness, then it’s best to clean your water system. But this need not mean hours spent with a scrubbing brush.
Citroxx Bio is supplied in a 1-litre bottle, and you add an 800ml dose to the water container. Fill it up with water then run it though the system to kill all the germs. Pop the remaining 200ml in the water carrier, top up with water and the system is ready to use. Citroxx Bio doesn’t taint the water but still kills all manner of nasty bacteria.
