How does it work? Justchlor needs only 0.6%(6000 PPM) salt to produce sodium hyperchlorite through electrolytic process. Salt levels are only approximately 12% of sea water. When your pool pump is running, water passes over the electrolytic cell and produces chlorine, which is pumped back into the pool. Safe You no longer have to store dangerous chemicals. It is like swimming in a giant teardrop, which is much healthier as salt is a known disinfectant. No gas is generated when water flow stops (automatic cut out sensor). Economical Cost effective compared to Chlorine costs Healthy Many skin irritations are eliminated. No unpleasant chlorine odours or eye irritations.
