Dry rock to a established tank

[JKDMan]

can i add a piece of dry rock to my established tank without a parameter issue? I have some dry rock from my old tank that I didn't move over when I downsized. Can I add some (a small amount) to my tank without causing problems?

I have in the past with no issues

Yes, as long as it’s relatively clean.
