Hi guys.
Almost over night, brown spots have started to appear in our appear (see attached).
We only just moved in and only recently learning how to care for our pool - this was at a point where our chlorine levels were quite low.
Is this algae? I tried scrubbing it but it wouldn't come off.
I tried rubbing Vitamin C tablets as apparently it could be a metal stain, but that didn't do anything.
Any help and advice would be great!
