Hello Rc Peeps. I have a question. I am moving my diplay tank from a 125 to a 75. Why am I doing this you ask? Well My 75 Gallon has a sump setup and my 125 does not. I am going to use my 125 at a later time after I get the correct type of cabinet and the correct hardware that I want. So my questions are this. Any answer for my questions below would be greatly appreciated. Thanks.
1.) Should I continue to use media from my canister in my sump?
2.) How to avoid a Cycle of the 75 gallon?
3.) Should I use new substrate or continue to use what is in my 125?

I would use everything except the sand.
Toss the sand.
I would use half the water and then make half new water.

I'm a big confused. Is the 75g already established and running? Or is it a brand new setup on an empty tank?

How old is the 125 setup and what shape is it in? Any ongoing issues you're battling?

Question why not move the substrate?

Substrate tends to act as a sink for detritus and gunk. It's hard to move substrate without releasing all that back in to the water column which would likely cause a major crash. It would be helpful to move a few handfuls of the sand to transfer bacteria and other beneficial life to the new system, but moving ALL the sand from one tank to another is usually messy and unproductive.

Is the new tank going in to the same spot as the old one? Ideally, you would set the new one up, cycle it, then move all the livestock over. If it's going in to the same exact spot and you can't do that, I'd set up a temporary holding tank of some kind - a rubbermaid bin or something. Put heaters and a pump in it, transfer your rock and livestock to it, then swap the tanks and move everything to the new tank.

I'd plan on doing several large water changes during the first week to keep things settled.
