Quick tank setup

[Azilla]

Have a quick question about tank setup. If i take my liverock and water from my 75gal tank thats been setup over a year now and put it in a 20gal tank while i do my clean up will it cycle??? I do have a new bag of Sand i want to make live was thinking this would be the best time to add it?? with new sand it wont have to cycle will it?

If you transfer the live rock I would be sure to add 50-75% of the total water volume from your existing setup and the rest can be made up of new water. So you could do a 10gl water change on the 75gl and use the old water in the new 20gl.
The sandbed will go through a diatom cycle from the added silicates of the new sand. This is normal though so expect to have some brown film on the new sand until it's a healthy live sandbed.
