Hi, we ran across the BBB pool approach 8 years ago when we first installed our pool, and have never looked back. Our pool has always been sparkly and gorgeous...until this summer. Last two years were not banner pool-care years, and so I got through the summer by just adding 'the usual' amount of liquid chlorine and muriatic acid. The pool still had beautiful water but this summer, we have divots in the bottom of the liner (lots of them) as if the sand is settling underneath the pool These spots are getting dark TOUGH algae (I'm assuming) in them, and if I get the dark spot off, it has a chalky gray layer (rough to the touch) underneath. I have tried everything from straight muriatic acid through a dish wand soap applicator brush, to toothbrushing (almost drowned with that attempt ) to magic eraser. If i use a hard unsharp stick like the back of a wooden spoon, I can get the dark spot to lift off but not the gray layer (sigh).
Just ran my levels and they are a mess. I need to know what I can do in the next 3 days before we close it to possibly work on the problem across the winter while it's covered up. Anything that will maybe eat through the gray stuff while it's dormant, so to speak.

We do routinely run filter/clean baskets/brush walls down/backwash accordingly. Have a hand-me-down barracuda that does a pretty good job vacuuming. Water always feels fresh/unslimy, walls also not slimy.
Hoping I can turn this around.
