The first thing that anyone is going to want is some reliable test results. You say that you don't have a reliable test kit "yet" so hopefully you have ordered the Taylor K2006. It will make your life so much easier with maintaining your pool.
With that said, if the results are anywhere close to being correct, there are several issues at hand. Low Chlorine, Low PH and low CYA.

I'm no expert but I can say that getting chlorine in your pool and raising your ph are going to be your first steps. Bleach and Borax is the way to go. Bleach will add chlorine and the borax will increase your PH. If you're using trichlor tabs then you are getting CYA but it takes a while for that to show up. Just keep chlorine in your pool to prevent an algae outbreak and get a set of reliable test results from a drop based test kit.
Hopefully someone with much more knowledge will chime in and give you some specifics on the steps you need to take and the dosages.
