I find if I shine a strong flashlight at the neck of the carboy I can see the tiny bubbles.It's usually easier to hear MLF rather than see it... stick your ear next to the top of your (open!) carboy and you should hear a faint crackling. If it's slowing down, it might be more of an intermittent soft pop-pop-pop. I would expect it to take at least a few weeks to complete, depending on temperature, pH, alcohol % and MLB strain.
