Chlorine isn't the culprit George. The culprit is too much lighting and improper tank maintenance. Chlorine was simply covering up the underlying problems you had, so when you eliminated the chlorine, you could see what was really wrong with your tank.
Think about it this way. If you had a dead body under your floorboards causing your house to stink of rotting flesh, would you just soak the carpet in bleach every morning so that the chlorine would cover up the smell? Or would you rip the floorboards up and get rid of the rotting carcass?
Rip the floorboards up George. Start again from scratch. That's the best advice I can offer.
