Hi, I am very new to this forum! I just purchased a 3 year old freshwater pool. In excellent condition with No corrosion. Is it OK to ust salt water? The pool came with a new salt chlorinator.. All of the underground bracing galvanised steel The uprights and capping is painted steel... Will corrosion be a problem? What can I do to avoud corrosion? Thanks heaps, Stuart
