As long as you have green, you still have live algae. Keep adding bleach to go back up to 20 ppm--if you let your chlorine yo-yo up and down, you're fighting a losing battle. test at least a couple of times daily and each time add enough bleach to get back up to 20 ppm.......the more often you do this, the faster it'll clear up. Once all the algae is dead and you have cloudy (but white, not green clouds) water, continual brushing and leaving the filter on 24/7 will get rid of the dead algae suspended in the water, which is causing the cloudiness. Be patient, it WILL clear up. Calling a pool service at this point is likely to end up with people dumping lots of other unnecessary stuff in your pool to further complicate your situation!

Be sure and keep an eye on your filter pressure......
