I've only been a pool owner for under a year... and with the help of TFP, I've learned A LOT. My water is finally where I want it to be... and I have a firm understanding of how different variables effect each other.
Now I've got a new problem...
Rust spots. I've read that they can come from a leaf left in the pool... or from other sources.
The part that concerns me is that they seem to be forming more along the bottom edge and not the very bottom (where you might find an occasional leaf... which I often get rid of quickly).
Could this be something serious like some metal rebar that is "leeching" or something else? I tried scrubbing at one of them with no success... albeit, I really didn't scrub very well as they tend to be in the deep part of the pool. Some are the size of a penny some are smaller some are the size of a quarter.
Any thoughts? What causes them, what have you done to get rid of them... how do you know if it's serious issue or a cosmetic one?
