Hi everyone. About a month ago I noticed this brown rust colored stain all around the edge of my inground pool liner. Now it is in the deep end as we'll. it won't brush off and shocking pool doesn't help I have even stuck my hand on the liner and it is smooth. Chemistry levels are:
Fc: 1.5
Cc: 0
Tc: 1.5
Calcium: 200
Ta: 120
Ph: 7.6
Cya: 70
I have been vacuuming every 3 to 4 days with not much leaf debris on bottom. Do top of pool with well water. But have never had this happen before as liner is three yrs old . Any ideas how to remove it?? Or what it is? It is becoming unsightly ! Please help
