New user. Love the site. First month in taking over for my "pool guy". Question:
I am finding a small amount of a light blue, granular (grains the size of very course salt or sand) substance in my skimmer bag and some quantities in the bottom of the pool. Any idea what exactly that is?
I haven't added salt (or anything else) in almost two weeks.
I am getting ready to add some Muratic Acid tonight as my pool seems to be a bit toward the potential scaling side. (I have also noticed a small amount of scaling on the bottom of the metal cross bar of my electric pool cover. This may have been there for several months.)
Latest tests: FC/TC: 5+, pH 7.8, TA 150, CH 430, CYA 50, Salt 2800
