If I don't destroy my pool, and myself, it is going to be a miracle.
The plaster in this pool is blue in color, and somewhat mottled with age. There is an area at the deep end that is brighter blue than the rest of it. I think this may have happened when I added acid at one of the jets at the deep end. At the time, I did not know you were supposed to use a brush to move the acid around on the bottom of the pool. I did use a net to blend it in, but I don't recall how deep I went. This is also the time I got acid fumes in my eyes, so I was not thinking the best at that point. I didn't really notice it before, but I recently have been changing some of the water, and noticed it. Maybe it has something to do with the tap water coming in, also at the deep end (although the brighter area is at a right angle to the tap water flow).
The pH has been very high recently 8.2, and I have done water changes, because I just could not get everything balanced. cYA was 160, and CA was 750.
My water is now:
I don't know if I should lower the pH of the pool to see if the color will blend better. Let me know what you guys think.
