Had metal stains on my liner. (Tested as Copper)
Used Metal Magic and it worked very well.
Stains reoccurred after chlorine added. My guess is that I added it too quickly?
Used more Metal Magic
Now I'm having a problem with getting an adequate free chlorine level.
pH 7.2
TA 70
Total Chlorine 1.0
Free Chlorine 0 - 1.0
CYA 70. Up after using chlorine tablets and stabilized shock. Using bleach now
Water is crystal clear and no stains
