Thanks for the quick response. Our pool builder has now put a total of 4 bottles of Metal Out (is this comparable to the products you mentioned). He talked with the local supply store, and they told him this was normal for pool in this area using a well to fill a pool.
He drained the hot tub to check the plaster, and it looks good no staining.
You said to lower the pH, I mentioned this to him and he was hesitant saying he has it perfect now. Will lowering the pH help to keep the plaster from staining or is there another reason.
He was also about to add Calcuim Increaser, I stopped him from doing so.
