Are my rocks reef ready/safe?

[Ezreal]

I have had these rocks first in fresh RODI water then RO with peroxide then saltwater for over a month now.

They don't smell funny but the big rock looks a little odd. It's clearly a dead coral of some kind that grew over some other rock. I feel like I have seen that darker base rock here in FL before but I can't remember if it's natural or manmade.

 

[Ezreal]

Anyone?

It sounds like your process was a good one. If you want to be extra sure put the rocks in a container of saltwater with a heater and pump and after a few days test the water. I'd at least test for ammonia, nitrite, nitrate and also phosphate.

Don't got a phos or nitrite but got nitrate and its 0

Really hard to say bc any rock that has any metal deposits in it will not be safe for corals. If you dont know what kind of rock they are and what their composition is, then it's a gamble.

I suppose if you love the rock that much, submerge in SW in a bucket for 1-2 weeks, then get a ICP Triton test and test for metals. But that's a lot of money just for rocks

I imagine if there were metals the coral skeleton wouldn't have grown around it and there wouldn't be (now dead) clams in it

The rock was collected from a beech in FL by a friend. Yes yes I know about the laws but I couldn't drive back to return it and she would have thrown it out otherwise. So I figured I'd clean it up and and re use it.

I do have another rock that seems to be made out of the same stuff so it's possible that's the native rock?

Just not sure. Would love an expert opinion.

Here's the other rock from the same spot

No experts?

I live in Florida and that’s common rock in my area, don’t use the rock it has metal deposits in it, the coral skeletons are good.
