I am wrapping up an ascorbic acid treatment on the pool at my recently purchased home. The treatment has gone very smoothly & chlorine demand is now close to normal. Though this is my 1st AA treatment on this pool, it is definitely not my 1st adventure with AA but this has been the easiest by far.
My question is, there is a stain (actually about 3 very close together) on the bottom of the pool that were not affected by the treatment. There were many stains in the pool that were MUCH heavier & those have all disappeared & the rest of the surfaces are now pristine.
I am assuming this is a different type of stain. what is the best way to figure out what it is?
