I have a two year pool where I have struggled to control the rise in PH since the start. I have tried to lower the TA now below 100ppm which has helped some but I am concerned about the impacts of low TA on the pool surface, equipment and swimmer skin/eyes. Can anybody share their expertise?
Issue 2: I have a wet edge plaster in pacific blue color but have been seeing white blotches (increasing in size with time) show up all over the pool. They have treated with dry acid and MA but no impact. I am not sure what is causing it. Could there be something leaching from the plaster that is also causing the PH control issue I mention above?
