If you where to set up the tank and get everything ready for the addition of the LR
it would be better. I have yet to see freshly harvested rock make it's way into Canada without alot of die off so I wouldn't prep too much. Your going to get a complete cycle when it's added anyway. The only real precaution you can do is be prepared with plenty of SW
for water changes. That's going to be the best method for preserving your wanted hitchikers. It will not
impede the cycle either.
