Not looking to hijack the thread but could you please explain the purpose behind this process ? Is it necessary or does it simply speed up the cycle time ? I'm setting up a 90 gallon and ordering about 60lbs from Eli and wondering if I can simply let it cycle in the new take over a few months with seed rock or should I be doing this process prior ? 
 
thanks, 
Nick.
