Serious Stain Prevent helps prevent staining by "Locking up" mineral discolouration caused by dissolved metals, bore water and iron leaching etc. Especially in heated pools where metals plate out easily onto the walls and floor. It contains no phosphate based acids that provide nutrient for algae unlike other products. Regular use also prevents scale build up on salt chlorinator electrodes. It is suitable for all pool & spa types. For high metal concentrations use after treatment with the SeriouStain Remover to chelate excess metals.
