what i want to do is when i move in a few monthes i want to setup and let it cycle with all new live rock and add this rock again later. i will google. but does this kill the rock? im not concerned with organisms as there will be more on the new rock that will continue to reprduce. im hoping.

In my experience, the coralline is a write off after a very short period of time, and takes a few months to come back.

I agree with Myka on the coraline, I just pulled about 40 lbs of LR out of a tupperware container that I had it all in with the lid on for about a month while I worked my new display tank in.
The coraline was all gone, there was still a little aiptasia which had all turned clear and a few fanworms still kickin it and I have also seen some bristle worms as well, there was still some macro algea intact as well,though it looked like it was on it's last legs.
I thoroughly swished this LR in a fresh bucket of SW piece by piece right before putting it in the tank and was amazed at the amount of crap that came out when I did this, the water also smelled like a sewer once it was all said and done too.

I'm pretty sure that all the detrius that came out of the rocks is much better off down the drain than in my tank.
I hope.:question:

My experience with cooking LR is after only a month, yes it will stink, and alot of crude does come off the rock. As to the coraline dying... well i checked a couple days ago and i still have coraline on the rock and its been cooking for 2.5 months. I do 30% regular water changes every 2 weeks.

I had like 30 dead worms at the bottom of the container as well. :)

I was changing water almost every 2 days in mine, really wanted some squeeky clean rock for the new tank....
wonder my my coraline died offr so much faster.....

thats odd.. not sure why your coraline died off but you got me kinda worried, haha.

the feeling is mutual....lol

The coralline will turn white, but shouldn't take long to come back. Cooking it for only a month is useless.

I have at least 100 pounds cooking at any time. I cook it for as long as it takes to not test any nitrates or phosphates. I change the water once a week at the minimum. run a skimmer, heat the water, and have a couple power heads going. Every week when I change the water, I take the rock out, scrub it with a brush, and rinse it in clean water.

The rock I have cooking right now is the worst I've ever done. Its been cooking since October 13th, and still testing Phospates at 0.25. It should be done in another 3 weeks to a month.

Noone here said that they were cooking for only one month...lol.
where did that come from>>?



lol.

You mentioned that you had a lid on it for a month. I just wanted to throw that out there so someone didn't get the wrong idea and think they could cook it for a month, and all would be fine.

I had one person contact me thinking that cooking live rock was done in the oven.. The internet is a great resource for information, but sometimes what you type, and what someone else reads are two completely different things.
