The pool is being delivered tomorrow! I have searched for instructions on how to START using chemicals from scratch in a new AG Vinyl pool, but find information on switching from one type of chemical to another, starting in something other than vinyl, or opening a pre-existing pool in spring that already have some chemicals in them. I know the good people of this forum have found checmical Nervana and I want the start the easy/simple/inexpensive way right from the git-go without learning the hard way as so many have. (My momma didn't raise no dummy!) Now how do I get rail "A" into slot "B".....?
