AGP electrolysis

[Tom Morgan]

I have small holes in my aluminum above ground pool. I'm sure it's electrolysis because of the white residue. Can I save this wall?

I think you mean galvanic corrosion...normally galvanic corrosion only occurs when dissimilar metals are in contact with one another. Can you perhaps post some pictures of what you are seeing and add more information about your pool?

Also, how are you testing your water chemistry and what are your current levels? Metal corrosion is almost completely dominated by pH, so water balance is important.
