ChloroKlean Chlorine Dioxide

ChloroKlean stabilised chlorine dioxide concentrate for pool and spa engineers carrying out oxidative cleaning of water systems and pipework. It activates in situ after entering water below pH 10 and can be used with chlorine, bromine and salt systems. Trade buyers can order 0.5L, 1L, 2.5L and 5L containers, allowing stockists and service firms to match pack size to each job. The range gives specialist contractors a compact liquid line for addressing organic loading and biofilm during planned system care.

Available formats

Available in 0.5L, 1L, 2.5L and 5L bottles.

Choosing between chlorine, bromine and chlorine dioxide

A stockist's view of the three sanitiser chemistries: where each sells, how it behaves in heated water and what it costs the end user to run.

What mattersChlorineBromineChlorine dioxide
Typical useRoutine daily sanitising at the lowest costSpas where a gentler, more stable residual is preferredClean-up treatments, biofilm removal and recovering poor water
Working levelFree chlorine 3 to 5 ppmTotal bromine 4 to 6 ppmApplied as a periodic clean-up dose rather than a maintained residual
Behaviour in heated waterDepletes more quickly at spa temperaturesHolds its efficacy in warm waterStrong oxidiser; the usual choice where biofilm is suspected
Dependence on pHMost effective between pH 7.2 and 7.6Tolerates a broader pH windowPerformance changes little with pH
SmellChloramine odour develops if combined chlorine is not oxidisedLess pronounced than chlorineLittle odour at recommended doses
Running cost for the end userCheapest per weekA little above chlorineHigher per dose, offset by infrequent use
