I am trying to figure out potential causes/solutions for this. White plastic in my pool has turned a yellowish/brownish color. The pool cleaner is the most noticeable, though it's starting to happen on the cleaner hose, and plastic on returns and such.
The basic water chemistry seems correct, though I have not done extensive testing to see about metal in the water. And I feel like this could be something to look into. There is some spots in the pool where there is rust/iron problem. I bought a house with the pool already there and obviously something was done wrong in that regard. The waterfalls that come out the side have rust stains coming out of them and a couple smaller areas of the pool. My assumption is this is some kind of metal or rebar that was not properly protected or used. I have not yet checked into fixing those issues because I imagine it would be extremely expensive to fix since the problem areas are buried under concrete.
But the actual water clarity seems okay. The water does not have a rusty, disclored, or strange look to it. Is it possible some rebar rust could actually be affecting the white plastic parts in the pool? And if so, is this issue merely cosmetic or should I be more concerned to stop it immediately?
Maybe this issue is more normal than I realize and I shouldn't be concerned at all. Do other people here have an issue with their pool cleaner for example turning from white to a more yellowish/brown color?
