Excellent, off to a great start! I am sure you will have lot of fun come July 4th.
Get you PH and Alkalinity levels in the right direction, then get some liquid chlorine or bleach into it to get things started. It will much simpler to maintain the levels once you get the proper test kit, but that will take a good week to get. But no reason to not get things started now. If you do not have a local place that sells the kit, then you have to order it, and that is a wait for it item then. It will all come together in the end, enjoy!
