1) The product can be dosed directly into the pool without pre-dissolving. It should always be used when bathing has ceased. For outdoor use, avoid facing the wind when dosing. 2) Calculate the volume of water in your pool (if in doubt, consult Howards Hydrocare to help you work out the pool volume).
3) For cold water (below 20°C) or non-circulating water, pre-dissolve in a plastic bucket uncontaminated by other chemicals (or other types of chlorine) and distribute uniformly round the pool .
