Tank swap nuked tank

[tim the toolman]

This is interesting to read and Im hoping some others chime in with their experiences. I am about to do something very similar with my current 180. I am planning on removing everything into totes/another tank I am setting up temporarily to hold my fish while I do some upgrades to my tank.

So I guess my questions are:
1. did you rinse the sand at all beteween tanks?
2. How long did you have your rock or sand out of the water during transfer
3. How old was the original tank

Anyone with safe transfer info who would share their insight would be appreciated.
