Cycling Question

[ArowanaLover1902]

I plan on moving over to a my new big reef in march. Here are the specifications of my tanks:
Current: Biocube 29 (1 year old)
- 20 gallon display and 3 gallon sump for 23 gallons total
- 15-20ish pounds of live rock
- no clue how much live sand, maybe around 10 pounds
- coral (LPS, softies, shrooms, and zoas)
- fish (clownfish, watchman goby, lawnmower blenny (Who is priceless to me as he eats cyano), and my tank favorite, a four year old royal gramma
- feather duster worm
- porcelain crab
- hermits
- snails
- various little live rock critters

New: Custom tank, stand, and sump of a craigslist guy (total genius, tank is amazing, everything every reefer could want)
- 35 gallon shallow display
- 15 gallon sump/refugium
- 50 Gallon total volume
BUYING IN MARCH FOR 35 GALLON
- 30 pounds dry rock
- 60 pounds live sand

If I was to take all the sand, rock, and water from the Biocube 29 and just put it into the other tank would I have to worry about cycling at all. That's a lot of stuff and water volume would go way down with 50ish pounds of live/dry rock. I've got a few pieces of super healthy live rock and my sanded is full of critters. I'd move all my biological filter media over too, just to help even more. My question is, simply put, could I move all my current tank to my new larger tank in under a day (or however it takes for the actual physical labor aspect to get done) without damaging my livestock?

You might run a mini cycle, or full, it’s hard to say. As for the livestock, i’d Leave a small rock in each tank and leave the fish in their tanks til your sure there’s no cycle.

The bacteria lives on the surface of your rock, sand and other media. So as long as you have no die off you should be okay. Might just want a bottle of extra bacteria on hand in case of an unlikely event.

Yeah I'd dose some when I was doing it for sure. This is something I need to be sure about though. Can't start it and find out it doesn't work halfway through.

@Randy Holmes-Farley what is your professional opinion?

Well I'll probably end up just doing it, after all, there isn't much to cycle
