After trying to clear some very murky water it was decided that the pool would be drained! The pool just wasn't becoming clear after turning light grey, even holding shock level for multiple days on end.
There was lots of sand and gunk all over the surface and strange bumps, almost the appearance of tiny barnacles, covering all of the walls and the floor of the deep end. There is also lots of discoloring which is also more prominent in the deep end.
As far as where to go from here I'm a bit lost. Should I:
-Scrub off all the bumps and refill?
-Paint over the bumps with pool paint (epoxy or latex)?
-Scrub and then paint?

Here is a closeup of the bumps, with hand for size comparison
The bumps do come off, but not easily. It seems as though it would take a long time to scrub off and would require some sort of wire/metal brush/pad. Another option could be a pressure washer but I don't want to spend the money renting one if it's not worth the hassle or time. What are yout thoughts TFP?
