Always ensure proper safety measures are taken when handling chemicals and consult your pool liner manufacturer's guidelines.

by taking the liner away!
As far as I can tell, it is not structurally harmful to vinyl pool liners, but can fade their coloring. The first year I had a pool, I made the mistake of dumping 1/2 pound of calcium hypochlorite (bleach) in one spot in the pool, which caused the liner to turn from blue to white, but did not cause it to leak.
