How long should I boil live rock for?

[Mechaninano]

So I purchased some live rock that had aiptasia on it. I put it in my brother's tank and the aiptasia exploded! Its every where (sorry Corey). So I have approximately 40 lbs of live rock covered with aiptasia that I have decided I'm going to boil to get rid of them. (I've got another 40 lbs of pest free live rock that I will use to seed the boiled rock for my tank start up). So my question is, how long should I leave my rocks in the boiling water? (I know about the hazards of boiling corals such as zoa's, the only thing on the rocks is aiptasia and a few zenias). Any input is greatly appreciated.

Thank-you.

I would hazard a guess that after 10 seconds, anything on the surface would be dead

But what about those sneaky ones deep in the crevices of the rock?

Well longer would be better, but why not just leave it outside for a while? A week say, give it a rinse then use your dead rock?

Because I'm really impatient

(and I love the smell of boiling rock...it really reeks!)

Was wondering about why the rocks were litterally boiled. But then there are a heck of a lot of ways to get rid of apastias, half of which don't involve killing everything on the rock.

It was either boiling or a vinegar bath (the vinegar probably would have smelled better, but I didnt have enough). I wanted to make sure I got them all (there were a lot... hundreds... maybe more, the move really stressed them and they spread so fast). With my luck, leaving them outside for a week one or two would survive, so I thought better safe than have them come back. I have read so many posts about people having them and not being able to get rid of them, and the majority of people said that if they had to do it over again, they would start from scratch (at least thats how I interpreted the posts and threads that I have read). I really didn't want to regret it later when the tank is all set up and established.

I used Aiptasia X on my tank, it did a great job at first. Killed all of them first try, but they musy have released a bunch of spores while dieing, I now have 10 times more then I had before. Pretty frustrating.

I would have done a vinegar bath before boiling. At least the anaerobic bacteria would have survived, so the organic leech from the rock wouldn't take so long. You're going to essentially be starting with "dry" base rock that still needs to leech.
