New Aquascape into Mature tank question

[Djalexchang]

Hello, I currently have an innovative marine 40g all in one tank. It is about 3-4 years old and I wanted to replace the rock scape. Remove all of my existing rock and add in a structure i made out of Haitian rock. I put the haitian rock in a separate bin and did a fishless cycle using Microbacter Xlm and their ammonia nutrient liquid. I tested it daily and a little over a week the rock is cycled

I wanted to know if I were to remove my old rock and replace it with the newly cycled Haitian rock, would I go through another cycle or will I be fine?

you would likely go through a mini cycle as the bacteria on the rock catches up to what was the bacteria on the current rock

Depends on your current bioload and whether you have any other bacteria havens (like sand bed, bio balls, or ceramic type media). You can reduce your chances of something going amiss by throwing some sponge filters in your sump for a few weeks prior (or any other medium that will allow bacteria to colonize it), or keep some of the existing live rock in your sump for a few weeks while the other rock builds its bacterial colonies up.
