Re: what to add first
additional information....while waiting for a reply, I decided to add bleach because I don't want any growth to start. after adding one bottle of 8.25%, the water turned a slight tint...like very light greenish dingy color. please advise as to how to proceed

Re: what to add first
Your pool turning slightly green after adding the bleach means, I'm guessing, the copper needs to be addressed. I'll let one of the "metal mavens" help you with that. Otherwise, your numbers are good for opening. Your CYA is a tad low, and your pH is a tad high. but neither is bad.
