hi ive just changed my substrate and i was wondering will the tank have to be cycled again ?

You will have lost a large quantity of your bacteria so a cycling process is good if you haven't fish in the tank allready. However if you kept the same plants, other decorations and filter the cycling process will be jump started and you therefore have to cycle your tank for a much shorter time.
