I would also add more than just a few lbs, but you could wait on that. Try to match pound/gallon what you have in the 20, eventually, IMHO.

I agree with this, if it is established rock from a running tank and it is going to be out of water for a very short time (less than say 3 hours) then thewre won't be any die off and even if there was a tiny bit there is more than enuf bacteria in the rock to handle it.

this I disagree with, I have set up a new system (either from moving or what ever) about 5 times now and every time I use 100% new salt water. I have never lost anything and all I worry about is getting the PH, Alk and Temp the same in the two tanks.

changing tanks is a perfect time for that 100% clensing waterchange
