I am getting ready to start my first spa up, found this site awhile back and you took great care of my pool change over to salt. I have a two person spa that I have basically rebuilt from the ground up and hope to start adding water this weekend. I have no idea of what I need to get this thing going. I know there is alot of calcium in the water we are provided, but have access to a deep well from my neighbor. So what do you recommend I buy and keep on hand to keep the spa clean and safe for use? The pool company coming tomorrow and am sure they will try to sell me everything under the sun. I don't want to here them tell me to buy all kinds of stuff that I really do not need so here I am asking for the best help I have found on the web.
