Your on the right track. When you add bleach the first couple of times it really reacts to the baquacrap by changing to all kinds of colors. You just need to keep adding chlorine to keep it up between 12-15 ppm. If you have a vinyl liner I wouldn't go over 15 ppm or you may bleach your liner. You really need a good test kit to measure higher chlorine levels. Read the other posts in this section and you will run across how to dilute your pool water to test your chlorine level with the kit you have. I just don't know how accurate it will be.

Four years ago I was at this point and I have never regretted changing. Best of luck on your mission!! You will have nice clear water before you know it!!!
