What kind of test kit are you using? It sounds like maybe it is an HTH 6-Way? Take a look at the chart at this link. It shows how to decipher colors on the OTO test that are past the colors on the comparator tube. http://pool9.net/oto-chart/
I wish you hadn't used the copper algaecide. I bet you didn't know that it is copper, and not chlorine like most people think, that stains things and turns blonde hair green!
Tell us exactly what all you have put in the pool, meaning ingredients and not just 'shock.'
Tell us what size pump you have and what kind and size of filter. While you are trying to clear this up, run your pump 24/7, cleaning the filter as needed.
In your pool, each of the 121-oz bottles of bleach will add a little less than 3ppm of chlorine. Use that as a reference to help you figure out doses of bleach to add. Try and keep your chlorine in the 15ppm while you are trying to clear this.
Stay out of that pool store!
