As long as you don't have any inverts or fish in the tank, I think it's safe to add the 10 lbs...it should not hurt your existing LR. The tank will most likely cycle again...so you'll have to wait until nitrite and ammonia are back down to zero, and nitrate is at a safe level, before adding any lifestock.
HTH.

Also, there's nothing wrong with getting into the habit now of doing regular water changes.
Good luck, and keep us posted!
