You should be testing for Ammonia, Nitrite, Nitrate and PH before you should even think about adding livestock. How much (weight) liverock do you have in the tank? If it was completely dried out then it will take a while for the tank to cycle, and until the tank has cycled you shouldnt add any livestock. Alage is usually the sign of a cycled tank, and thats why you arent seeing any.
Have you read the pinned topics at the top of the forum?
Edit: just read the last bit
You should add your live rock as soon as possible, also stop using the nutrifin stuff, let the tank cycle naturally.
