I almost called it the Belgium method. Tssst. What are we making waffles or somethin? Tssst...

I have had my 13.5 Evo running for 2 years now and have decided I want something a little bigger and something that will give me some better options for returns pumps etc... Things are getting tight and making maintenance more difficult so bigger would help me out. I am trying to wrap my head around transferring everything from the old tank to the new tank and wanted to run it by this forum first. I have watched videos and read about people using live rock to skip the cycle phase of a new tank. It seems logical and technically I have done something like that already when I did a rip clean of my Evo last spring and everything worked out fine. However the volume did not change in the tank where this time I am going up by 12 gallons. Regarding this method I have read something on the lines of "The typical rule of thumb is to use from 1-2 lb (0.45 to 0.9 kg) of live rock per gallon (US) (3.7 liters) of aquarium water depending on the density of the rock"

My plan is to move everything in this tank to the new 25 gallon tank. I am not sure about moving the existing sand bed even if I rinse it. Would love feedback on that. I plan on getting new sand to put in. I also want to get a couple more small pieces of live rock to throw in the tank so my acans have something to grow on. I will NOT be adding any new live stock to this new system for a bit and if I do it will be a peppermint shrimp and maybe another Urchin.

So I plan on moving my existing live rock with corals to the new aquarium.

I am not sure if I should rinse my existing sand and put it on top of new sand? Should i just go with new sand and ditch the old sand?

I have a drop in algae scrubber that uses an airline that has growth on it that will be going in the filtration section of the tank. (see image)

I want to bring over my sponge/mechanical filtration over to the filtration part of the tank cause it should have bacteria on it. (I think?)
(see the green foam stuff under the filter floss)

I am going to make sure the new water has the same salinity as my existing tank water. I plan on keeping my lights down low and let things acclimate for a couple weeks.

So in theory people can do all of this the day you put water in a new tank and it is supposed to skip the cycle process. But I am a little apprehensive about it cause I am increasing my water volume by about 11-12 gallons and not sure I will have enough bacteria on the rocks I have. I can add some new small live rock from a local fish store to help.

Will I be okay using this method to skip the cycle or should I just wait 2-3 weeks? Again I will NOT be adding new livestock to the tank. Just what I have already.

Thank you for taking the time to read this and don't worry if you think this is dumb or whatever. I won't get offended. I am a rookie and still learning.

Move the rocks. Everything else can be replaced with new. The sand and filters aren't going to make enough of a difference to be beneficial. If using established rock, there's no need to worry about a cycle.
