Adding more rock to a mature tank.

[Tomb85]

Would anything bad happen in my tank if I add another 25kg of rock to a 450ltr system? I assume it would raise tank parameters abit but hopefully not to much. Long term benefits will be alot better I know. I currently have a minimalistic rock work but need more rock work for fish and corals.

Is the rock live or dry?
Do you intend to add it all at once?
personally I would add a bit at a time, check all parameters leave it a a few days then repeat
