We became pool owners when we got our house in 2007. The pool was a little rough but relatively ok. Due to our failed attempts to care for it (and subsequent neglect due to frustration) it has developed some stains. From what i'm not entirely sure. I tried testing to see if it was copper, which is pretty likely, but my test was inconclusive. I have no idea how old the finish is but it is kind of rough though not flaking off or chipping.
We have now developed some wear marks around the water jets. What i'm not sure about is if this is all just cosmetic or if things have gotten to the point where we just have to replaster. We have no water loss and the wear is actually more of a green color (though not algae as its this color even when the pool water is perfect). I almost wonder if it is either another layer of green plaster underneath the white or if we have a calcium buildup (had really high levels for a long time) and that the jets kept whatever is actually built up all over the pool from appearing in their stream. Likely, it is a combination of things one of which being the plaster has about had it!
Here are some pics.
I appreciate any insight you can give me. I'm sure no matter what it is, it is partially age and mostly just poor maintenance. I'm looking to get on top of things and follow the advice I've found here!
