Little background: I have been taking care of my pool solo for 2 little more than 2 years, but haven't been as consistent as I should be. The pool may have had very low TA levels and calcium levels for an extended period of time.
My current numbers are:
FC - fluctuates daily but right now about 9-10
pH - 7.5
TA - 90
CH - 230
CYA - 110
The first 4 pictures are the one I am most worried about. These brownish/orange-ish stains started about 1-1.5 years ago, and started small but kept growing. It appears to be mostly a problem in the shallow end, not the deep, and seen clearly on the grout between the tile. Could this be some form of algae? Metal staining? Grout stripping away?
Please zoom in if necessary. I can upload the pics here in full 3-4 MB detail if it would be better.

These second set of 4 pics are another issue. The weird thing is you can see deposits on the tile ABOVE the water line, but below the water line seems to be clear (please ignore the little bit of debris floating on the water surface). On advice our old pool man (before I took it over), I tried scrubbing it with a stone (pumice?). You can see some of the tiles are cleaner in the center but it's impossible to scrape this away around the edges of each tile or in between the tiles.
