Technical characteristics

HTH Spa Flash Desinfection

To use while filling up the spa. Against Legionella
  • Instant dissolution powder, residue-free.
  • Very high available average chlorine content of 75 %.
  • The most concentrated hypochlorite available on the market.
  • Totally exempt of isocyanuric acid (stabilizer).
  • Compatible with any filtration equipment.

Use HTH spa flash disinfection in order to eliminate every bacteria (like Legionella) and micro-organisms that might be present in the circulation system of the spa.

At each spa filling :
Actuate the filtration and dust 25g (1/2 dose) of HTH spa flash disinfection per water m3 (1000L) straight into the spa. Let the filtration run for 2 to 3 hours and measure the chlorine rate. Make sure that it is back down to between 3 and 5 mg/L in order to go bathing. Then use your usual disinfectant.

Don’t mix a stabilized chlorine in solid state : hth spa blue label (dehydrated sodium trichloroisocyanuric or dichloroisocyanuric acid) with a chlorine without stabilizer: hth spa red label (calcium or lithium hypochlorite)
