Hi all, I'm new to TFP but feel it will be my new home for the foreseeable future.
The pool in question is for a house we're buying. We're in agreement of sales but now are going back and forth with some inspection related material. In the end, it's the house my wife and I want to be in. In any case, for the pool, there are large dark streaks running from the steps from the shallow end of the pool and from the overflow of the hot tub area. There are also a good amount of discoloration throughout the plaster of the pool. I had a pool guy come out and he said the streaks looks like it originated from someone laying a garden hose from the shallow end and the hot tub area already filled and it overflowed from that area. I asked him is it just an aesthetic issue or worse and what can be done about it. He said it's mostly aesthetic and an acid wash should blend most of the streaks/discoloration but it'll be difficult to totally mask it. Of course he recommends a complete re-plaster.
Here's a picture of the pool:
So what do you guys think? Is it just an aesthetic issue? Can an acid wash lessen the difference in colors? Or would a full re-plastering be recommended?
btw, I have no idea about the chemistry makeup of the pool water but it's maintained by a pool company and not the owners.
