Cycle question with cycled decor and filter

[Loach23]

Ok I'm upgrading from my 55 to a 120 gallon. Right now I have two emperor 400 on the 55.. So I'm rated at 800 gph With the 2. I'm going to use them both on the 120. If I use the filters, rocks, driftwood, and gravel from my established 55 how long will it take for the 120 to cycle. I assume a few days if I use some of the water as well am I correct. I figure it will be like doing a large water change

You might possibly go through a mini cycle but I highly doubt it. Just watch your levels to make sure.

I hope it doesn't. The only thing I'm changing is that in my 55 I have only gravel substrate.. And in the new 120 I want to do a dirt and gravel on top so I can have a somewhat of a planted tank
