Hey y'all and thanks for the help in advance!

I have a 5 gallon tank running for a month with 5-7 lbs of live rock, 2in base of live sand, topfin powerhead, HOB filter rated 100 gph. I'm thinking of possibly upgrading (next month or two, no sooner), but want to get all of my research done first. For my current setup, a 20 gallon tank will be my max; I can get a 20 gal long tank that actually looks a lot bigger then it is from my LFS. Also, my 5 gal is fully cycled. If I do this, I also plan on using the 5 gal tank as a sump. So my question is: If I transfer the water, live rock, filter and media, and live sand (and add more of course), will the tank have to cycle again? Do you think there is enough bacteria to support the new tank? I know that people do this for setting up smaller tanks, but I haven't heard of anyone going from a small to larger tank.

I know it would be more expensive, but if I want to avoid any major cycling, can I use live water? Such as: Nutri-SeaWater. Would I need to ensure that the whole tank is live water or just a percentage, like 50/50, 60/40, etc, etc?

Again, thanks for the help!

You wouldn't have another cycle unless you add more live rock. If you add more live rock the die off on the new rock might kick off a mini cycle. You can try to avoid that by moving it in water though. Adding dry rock won't kick off another cycle. Just remember to add slowly - one fish at a time and a few weeks between additions for the bacteria to grow with each one.

I personally thing NutriSea water is a waste of money. Most of your bacteria lives in the rocks and sand, not in the water.

Ok, gotcha. That makes sense! If I mixed dry rock and live rock, how long might it take for the algae and bacteria to really start growing on the rock?

That also makes sense too. And 25-35 dollars with shipping for 4 gallons is crazy!

Thanks for the input!!

If you add dry rock it will get loaded with bacteria pretty quickly, but the rock will continue to evolve for the life of the tank. For an example here is a picture of my tank over about a 2 year period. About 80% of the rock dry rock. Notice how the rock is always changing:
