Upgrading from 50 gal to 112 gal question.

[nanoreefbro]

In a few months I plan on upgrading my 50 gal tank that has been running for about 6 years to a new 112 gal tank. I plan on switching out the CaribSea sand that I have for Tropic Eden. I will be using the live rock from the old tank and adding some more live rock that has been cured for several months. I will also transfer my refugium from my 50 gal to the new tank as well. My question is will I need to cycle the tank again and if so for how long?

Yes, you need to cycle the new tank. How long depends on the tank... it could be a quick cycle since you're using cured live rock, your tests will tell you when it's done.
