Hello everyone, I've been lurking TFP for about a year now and 99 times out of 100 I find my answers without ever needing to create an account. I hate to have my first post be a "HELP ME" post but I just can't figure this one out. Alas, here I am.
I have a small in ground plaster spa. It has a salt system (archaic one at that). Literally over the course of a 2 week period it went from being totally fine to being almost completely stained blue (walls AND floor). Maybe coincidentally, but maybe not, at the same time the salt system started to NOT generate chlorine anymore.
I personally tested the following:
All chlorines: 0
Then I brought a water sample to the nearest Leslie's today and they checked everything they could, they were conveniently out of the solution to test copper/metals. They came up with the same exact results as myself and said it's most likely copper staining and that I could correct the problem with a partial bottle of Stain & Scale2. But my dilemma is this: The copper staining had to have come from somewhere (definitely not from an algaecide seeing as how I've NEVER put any in the spa) that I don't have any control over. So even if the Stain & Scale2 works over the 3 week period it says it will, eventually the staining will come back, right? I mean it's only logical that eventually the Stain & Scale2 will no longer exist in the water and that copper staining will find it's way back again.
Any help whatsoever would be greatly appreciated. Maybe some of you have a better understanding of what's going on. Maybe the inoperable salt system DOES have something to do with it. Maybe I'm just crazy? haha
