The white flakes start floating around when I step in, which is 100% nasty. The owner said the water is murky due to the rain messing with the pH, and indeed, it has been raining the last couple of days, but no clue about the flakes. The pool guy apparently comes tomorrow to do some regular maintenance. Are these flakes and the murky water something a simple maintenance can resolve or should I ask the bnb owner for something more?
