The most likely causes of a shift in pH are: 1  Something in the water source buffering the water. 2  Something in the tank buffering the water. 3  or Something you are adding to the tank.
If the pH levels of your pool water are too high, the water becomes too alkaline and it starts to form scale on the surface of the pool and equipment. If the pH level is too low, then the pool water is acidic. This causes corrosion on the pool surfaces and the equipment in your pool thus damaging them.
