Chlorine & Copper Stains

These are some sites that we were called in to rectify, which had been either overdosed with chlorine and salt systems or other quick fix products. Please note that a lot of these pictures were taken of the long term effect of these chemicals or of pools that have a solar blanket that blocks the UV rays allowing chlorine to build up. The covered pools can stain within months of exposure to high chlorine as well as the lack of brushing. If you require a “hassle free” chemical that really works please refer to our bio degradable copper free 60 Day Water Treatment.


Chlorine stains are caused by overdosing of either Regular chlorine, monthly floaters in the smaller pools of less than 40 000 litres and salt chlorinators that have not been monitored properly. The main cause is not testing your water once a week. If you dont check your oil in the car engine weekly, it will also get damaged. TEST TEST TEST…I can not stress enough how many surfaces get damaged from chemical overdosing!!! The below pictures are just a few cases. Please note we can reverse staining on fibreglass by dosing the pool with a cocktail of chemicals. Please contact us if you recognize your symptoms here. Even if your salt chlorinator is turned on low in winter or if the pool is covered, it can still make high levels of chlorine resulting in damage to the surface as well as the cell or electrode. ( the worst cases are pools that have a solar cover that blocks the UV rays) This can shorten the life of the electrode by up to a year as the chlorine eats away the coating of the cell. We have seen hundreds of pools that are covered with massive staining. ( Partly from dirt and mostly from chlorine abuse)


Copper stains caused by pool products using copper as a chlorine saver.
