A pH of 7.0 is neutral - below 7.0 is acidic, above 7.0 is alkaline. The pH of our eyes is 7.2 . No wonder that the ideal pH for your pool is just that - 7.2 , and should be kept within the range of 7.0-7.6 . What happens when the pool is too acidic? (pH is low) If your swimming pool is Marbelite or plaster, the pool water will begin to dissolve the surface, creating a roughness which is ideal for pool algae growth. A similar result occurs in the grouting of tiled swimming pools. Metals corrode - and this includes swimming pool equipment, pipe fittings, pump connections, etc. As the swimming pool walls and metal parts corrode, sulphates are formed. These sulphates are released from the water onto the walls and floor of the swimming pool causing ugly brown and black stains. Chlorine, which is used as a disinfectant in the swimming pool water, is activated and lost to the atmosphere very quickly.
