Our pool was filled in October and water chemistry has been perfect and my husband is diligent about following TFP for chemistry!
About a month after fill, we noticed a halo around a ‘larger’ pebble in our finish. Only 1 spot on vertical wall of sun shelf (CL industries pebble). It never got much worse, never got better, about the size of a dime. We thought it may have been a void in the finish, especially since every other area is perfect. I’ve attached before and after photos the best I could get them!
Tried the vitamin C today and the halo immediately disappeared with that ‘larger’ rock remaining (we think it’s a rock) . My understanding is that it’s iron.
I’m worried this means the rebar may be coming through..? This is the only spot and everything else looks great!
If the halo of rust appears again around that same area, what is that telling me? If it doesn’t reappear, what would that tell me?
Since it’s on a vertical surface, we are able to rule out a metal object causing it, etc.
Your help would be appreciated!!
