What were the results from this am and after work? Did it drop below 16ppm today?
Dark green is a lot of algae to fix, it's going to take some time. If you fell below 16ppm you might have stalled a bit today as well. If no one can test and add bleach during the day, then yes absolutely add extra in the AM so that it doesn't fall below shock level. You are safe to add up to 29ppm (mustard shock level for 50ppm CYA) so don't worry about over shocking till you hit that nut :~}
I don't know if this would be right, but if you wanted to raise it to mustard shock level you might see quicker results. Again, I am not sure if this is a good idea but since mustard shock level is still safe for your pool... I myself might consider dosing it that high for a day or two and then dropping back to normal shock level for the rest of the process.
Also, as has been suggested make sure there is no debris in the pool, leaves and organic matter constantly decompose... and decomposition uses the chlorine you are intending to be used for the algae. If you have debris in the pool, once you get it out you'll see better results.
