Hi, welcome to TFP! What we call good and what pool stores call good are two different things! Could you please post the most recent set of test results you have? Also is the shock you are using dichlor/trichlor or calcium hypochlorite? Did you add all the shock at once or over a period of time?
In order to help us help you please update your signature to include:
pool type (above ground or in ground), surface (vinyl, plaster, or fiberglass), size in gallons, pump brand and horsepower, filter type (sand, DE, or cartridge), filter brand and size, and any water features, cleaning systems, and if there is a spa (attached or detached). Also please include that you are on well water or under water restrictions if those conditions apply to your pool. It will show up at the bottom of everything you post and it is easier for us to help you if we don't have to search the thread for this information.
