Welcome to the forum. Many people have come here with your exact problem.
I'm gonna ask you to invest just a little bit more. You need to get a good test kit. I have and recommend the TF100 from tftestkits.net. It will save you a ton of money over time, so think of it as an investment rather than an expense. Get the XL option and the speedstir, you'll need the XL option because you're going to be testing a lot as you clean up your water. The Speedstir makes testing more fun, reliable and easier. If you don't want the TF100, the Taylor K2006C is the only other kit that has all the tests you need. Be careful comparing prices because the TF100 comes with more reagents for the tests that you'll run more often, making it a better value.
That being said, once you've ordered your test kit, download the PoolMath app. Enter your pool information into it and use it to calculate 5 ppm of chlorine using whatever strength of bleach/liquid chlorine you are able to find in your local area. Add that amount to your pool every day (with the pump running) until your test kit arrives. Do not add anything else to your pool while you are waiting for your kit. When your kit arrives, run a full suite of tests and post them in this thread like this:
