Hi, I noticed this around the base of the exterior of the wall on my Saltwater 8000 pool. Pool has completed two great seasons, just starting its third. Wondering what these 'bumps' are. I have stone surrounding my pool, just a thin layer right next to the pool with a little landscape fabric to stop any scratches. I have a pic with the stone pulled away, and one without the stone disturbed, you can it gets air where some of this is, and no fabric laying over it. When I rub at it, there is no signs of rust behind it, and seems solid. It is only at the base of the wall, right behind that stone. Some form of corrosion? Is this a problem/something to worry about? or just something that happens.
This pool model is coated in a corrosion resistant paint and also rated for semi-inground installation (mine is not inground, only have enough dirt at the base to cover the base rail per my installers instructions.)
I plan on contacting the manufacturer if there is any issue or doubt here.
Thanks!
