Hi everyone! I'm relatively new to the hobby. About a year ago I set up my first planted tank - it's a 37 gallon which is 24" tall, I'm running it on a canister filter. Now that's it's filing out the plants are getting crowded and 'm finding it way too tall to maintain. I would like to swap it out for a 40 gallon breeder. My question is this: do I need to cycle the tank again if I move all the plants, hardscape, and filter to the new tank? The only thing that will be new is the tank & substrate. Thank you!

It should be fine to just swap everyone over. I would use as much water as you can from the current tank to ensure that it isn't too far off pH/hardness wise, would make it like doing a large water change.

You will lose some of the nitrifying bacteria from the substrate change, but the plants and the canister filter should be more than enough to keep it going, especially since it looks like you don't have a ton of fish in there.

You should be fine. I’ve started two tanks recently using pre cycled filter media all parameters stayed perfect. 
 

I checked with Aquarium Coop before I did this just in case.
