Instant Cycle - Switching tanks?

[Madreefer]

Sounds like a pretty simple tank transfer to me. Only thing that might give you some greif is using 100% new sand. As for the rocks just put in one new rock per week until they're all in there and you should'nt have any cycle nor spikes at all. Theres alot of threads on tank transfers that you can search and all are very informative. Or if you want just put a bunch of chemicals in your tank that are not necessary. Good tip is to not put anything in your tank that you can not test for.
