Filling new pool in Amazon

I am filling a new 45,000 gallon pool here in the jungle. We do not have pool stores here in the amazon to buy chemicals. I was able to buy 5 gallons of liquid chlorine, and some products called ph lowerer and ph raiser. I bought a basic chlorine and ph test kit. I have a Taylor k2005 kit on the way, but this is all I have for now. I am trying to get some cyanuric acid from the capitol city in a couple of weeks. The pool should be filled tomorrow. How much chlorine do I need to add for initial setup? How do I do this? Any help would be appreciated. Thanks.
