If it's still green, then you still have algae, and you need to keep your pool at shock level (that level depends on your CYA level--I'm assuming you have zero CYA, so that means keeping your chlorine at 12-15 ppm) by testing and adding more chlorine 2-3 times daily until it's cloudy blue. After that, the filter is gonna have to get the dead algae out--so it's going to take some work to keep the filter going. You might try turning the pump off, letting the stuff settle to the bottom of the pool, and then vacuming to waste to bypass the filter--otherwise, it's going to be a matter of babysitting the filter until it gets all the dead stuff out. You're doing the right thing, though--I understand how frustrating it is...just keep it up!
The bags of shock could either be cal-hypo (which adds calcium to your pool in addition to chlorine) or dichlor (which adds chlorine and CYA). They certainly don't have the same effect on my pool as "5 gallons of 12%", so I'm not sure where that came from. Stay the course with the bleach, and hang in there!!
