Ok I am a newbie so be gentle on me...lol,, here is my problems. I have a in ground saltwater pool with a swg..I keep getting a dirty yellow stain. I thought it might be scale so I called a pool guy to come check it out for me. He informed me that I have to much metal in my pool. He asked if I had sealed my rock from around the pool and the water fall lately... Answer was no... He said that the metals from the rock is getting on the kids feet and staining the plaster??? He tried some stain away...which I think is the same as vitamin c??? And got no results.. He wants to do a acid wash...
Next question.. My irrigation system pulls water out of a pond behind the house. I get some over spray into the pool when the wind kicks up??? Could this be another issue with the stains??
I hope all this makes sense???
