I added calcium carbonate to my pool to get the Calcuim hardness level up. It was in the low 100's and now it is 430. I noticed today that on one wall of the pool there are small white bumps that are hard. They cover the wall but have not started on the steps or pool floor. Is this calcuim plating out from the CH being too high now? I could scrub this off with a silt stone but that will take a lot of work. My PH is 7.5, chlorine is about 3 and I have a SWG with CYA of 40.
Any help on how to get this off of the wall without having to scrub it would be appreciated.
I assume I will need to replace water to get the CH down?
