Hi,
I tried the Vitamin C and it did wipe it away. When I rub it with my hand it leave a chaulky white on my fingers and I brushed it and the the water was getting cloudy. I went to the pool store yesterday and the following are the readings
FC 5.6
TC 6.0
CC .4
PH 7.1
Hardness 270
Alkalinity 120
Cyanuric Acid 80
Copper NR
Iron NR
Total solids 895
I add ph+ and the level now seems to be 7.2 I was also told to shock it and the level this AM seems to be really high over the 5.0
Thanks
