can 6 month+ dried out caulerpa rock come back to life?

[CTaylor]

Hi,
I want to use a frag rock (has holes to hold frags) in my newer set up, but I have no caulerpa in it at all (knock on wood) and I prefer to keep it like that. I have a frag holder rock that had caulerpa grow on it. I pulled all off that I could, but anyone knows that means there is still some bits of it remaining and will grow back. But it's been dried out for at least 6 months. Is it possible it's become spores and those spores can grow if I add this rock to my tank?

Thanks!

I soaked my rocks in vinegar and it killed any caulerpa pretty quick.

Thanks DaddiO
But even spores (if there is such a thing?) so the vinegar makes it so it's totally eradicated and none can survive at all? Nothing to grow and sprout even a few weeks later? Caulerpa ruined the look of my last tank, and I never ever want to see that sh*t again lol.

How long do I soak it and str8 vinegar or diluted?
Then how do I rinse out and get rid of all the vinegar?! .. I know people dose it, but I have no idea how that works, and I don't know if I want vinegar in the tank.

Thanks!

A good rinse with fresh water should be enough.

I soaked in straight vinegar overnite, then soaked in R/O for a week and set them in a warm spot to dry for a week.

Thank you . It's just the one Tunze frag rock, so I wont need a ton of vinegar, and no rush, so taking a week isn't a big deal. TY

If you are not in a hurry, just put the piece in a container with salt water, set it in a sunny window, and wait a week to see what happens.

Vinegar, Bleach, Hydrogen Peroxide, Muriatic Acid. Any of those used properly will take care of anything that might stand a chance at life.

Muriatic and to a lesser extent vinegar will not only kill most of the stuff on the rock, it might dissolve the rock as well, especially if calcium carbonate based.

Only if you leave it in too long:spin3:

Vinegar began to bubble with the rocks from the start. After 24 hours there was no damage.
