hth compared to sodium hypochlorite

More swimming pools world-wide are treated with hth calcium hypochlorite than any other sanitiser brand. Arch Water Chemists continually monitor and evaluate not only the quality and safety of the water but also the effect of this treated water on pipes, pumps, heat exchangers and tiles. It has always been the case that when the total running costs of operating a swimming pool are taken into account it can actually be less expensive to sanitise with hth. With lower water consumption, less heating bills, reduced maintenance costs and longer plant life – any water, whatever the extremes of hardness or softness can benefit from the advantages that hth offers.
