Tank Cycling Question

[nmore]

if we add water from the filter of a properly cycled tank to a new tank how fast will the new tank cycle

Do you mean water or filter media?

There is no specific answer but genrally a lot quicker.

Adding water from a cycled tank won't do much of anything. However adding some filter media from a mature filter (no more that 30% or you will loose the cycle in the mature tank) will help to speed up the process. As previously mentioned it is hard to put a number on it but it will be faster.
