Instant Cycle - Switching tanks?

[Coasting]

So I figured this week I would like to finally bring my new tank up to the living room and use it! Its been re-siliconed and looks good, and has now officially passed my leak test.

My current DT is 30ish gallons, new one is 65ish with sump. I really do NOT have the room to keep them both running at the same time. However I can keep the 30 running for a few days beside the 65 while it settles. I also have a canister attached to the 30 that I can transfer over to the 65 so it can share its bacteria (really no media inside it, its more of a pod fuge and some itty bitty bits of rock rubble) My goal is to be able to return it before my dates up on the receipt.

I will be adding more live rock to the system and using most of my current rock. I'm worried about getting a cycle from the new rock. Is there anything I can add that will instant cycle the tank? I have a few different bacteria type supplements. I know I should keep the rock cycling in its bin longer to avoid these questions and issues, but its a matter of space at this point, though if its the only option I guess I will have to.

Only fish in the 30 are a Azure Damsel, Grumpy female clown, and some type of algae eating blenny. My biggest concern is the blenny and not having enough for him to eat in the new tank (though hes super fat so hes probably got a fair reserve to live off...) And all my coral, the anemones, mostly lps, only sps are 3 types of monti.

So its not a far move, I will be using 100% new sand, but some rock from another source ( currently circulating with heater in a large bin in the basement ) I dont want my fish or coral to die. Never transfered tanks before, Help!
