Hi and welcome! First of all, don't add anything else to your pool yet other than chlorine when needed. Post a full set of complete water testing results and let us look at them. Use a drops based kit -- no test strips. Walmart sells a 6-way kit that will test what we need for the time being until you can buy a good kit. We recommend a Taylor K-2006. Repost with more numbers and more specifics about your pool and pump/filter and somebody here can help you out.
Also, tell us exactly (ingredients -- not just "shock") of what all you have put in your pool thus far.
