Added different rock to newly cycled tank.

[Relax4]

We had some coral from freshwater tank , we were told to boil it and it would be fine to put in tank . I’m worried though, that I just put fish and new corrals in there. Is this going to throw the tank into another cycle and kill everything ? The rocks I put in are to the immediate right and left in front of tank . Thanks.

I'd probably add each piece about a month apart, but that's just me.

Was copper ever used in the freshwater tank?

No or not that I know of

I agree that it's best to add dry rock slowly
