New tank upgrade

[thisguy1]

Hi everybody I have a question hope someone can help me with. So I’m recently just getting back into the hobby with an Innovative Marine nuvo 15 tank. It’s cycled going on 3 weeks with two clowns…but I recently had the opportunity to get the innovative Marine nuvo 20 tank an impulse buy and wanting a slightly bigger tank lol. But my question is can I move everything from the 15 gallon to the 20 gallon without risking a new cycle? Ex. Move all the sand, rocks, and water since it’s still pretty new. The tank move will take place in my bedroom so no driving or long distance involved just a step or two away

Theoretically, move everything that will have any beneficial bacteria(sand(questionable), rock, filter media) but get new water. You will still get a secondary cycle with ammonia/ nitrite rise but if you are keeping up on the water changes and testing you should be fine i think. Please someone correct me if im wrong.
