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. The water is not being sanitized, and we are throwing away our money by adding chlorine when the pH is too low. When we swim, our eyes and nose burn. Our swimwear fades and perishes. Our skin gets dry and itchy.
