We have been gone for two weeks. Being near the end of the season we didn't have anyone to come a care for the pool. Came home, and this is what I see. Water is clear, but this white spot is on the liner. Will not brush off at all. Has a pink tinge to some areas. I normally use the BBB method. Please advise me as to what I need to do. Please tell me I can get rid of this. This is a brand new liner. I am about to go test the water. I am expecting to see all levels off badly. I have had a hard time keeping stabilizer levels up this year, thus I have had a hard time keeping the chlorine in the pool.
Also, the white spot is hard. It looks like cracked desert sand.
