Hm... a little late to ask now, especially since you already added a fish and corals?
Anyways, it is possible that LR can cure in a matter of a few days if die off is minimal. What exactly do you mean when you say that all your levels seem "ok"? Do you have any exact numbers?
Next time, I suggest asking questions before you take any action... rather than taking action before you ask your question. It may save you a bit of headache in the future
