upgrading to a 120 gallon

[KAHASH]

we are upgrading to a 120 gallon from a 45. We will be using all of the live rock and the sand from our 45 gallon along with new live rock and around 80 more pounds of new live sand. Do you think that there will be much of a cycle? Thank you for any help you might be able to offer

well u will have a small cycle since it was only 45 gal. i upgraded from a 70 to 120 with all my lived rocks and sand and i had a small cycle, check your water parameters every 2 days and do a water change every week til u get the proper water parameters
