What is the best solution for dipping LR?

Short version question...what do I need to dip everything in to 'clean out' the LR? High salinity? RO? I've even read carbonated water?

Long-winded bedtime girly story version...

So for the last couple of months, I have been having a couple of minor issues. Lost a couple of small fish and had a couple of crabs die off. And when I say lost, I don't mean died. I mean completely disappeared lost. Recently, my girlfriend said she thought a couple of the corals actually looked smaller. I thought she was batty. Since then, they have bleached, bottom to top. I don't have many, so I wrote it off to unstable params that I haven't bothered to buy test kits for. I wasn't planning on putting any more livestock in the tank and have been planning 'the next tank'. I do about a 30% water change bi-weekly and check the standard params once a week.

I'm getting great thick coralline growth on one of the rocks. While staring at the growth I noticed a hole and three extremely small 'feelers' coming out. They almost look like miniature bristle star arms. Black and white stripes. I didn't think much of it. I've also noticed a white slime or mucus covering the rocks. More than a little bit. A couple of quarters in size worth. Lastly, some of my LR almost looks like it is bleaching.

I should have asked earlier...but hell, honestly this tank has been stable for a couple of years and I thought I was pretty safe. I did add a couple more larger pieces of LR after I got it. I was reading a random build thread and saw the above mentioned descriptions...mucus holes and disappearing fish. This guy is pulling these things out of his 220 for the better part of a year now. Some a couple of feet long.

The feelers on the front of this lovely little critter are spot on for what is coming out of the rock. And where there is one worm...there are a truckload. (You should see my bristle worm collection in this little 20g.) I've also found my third gorilla crab, so I was going to get at him anyway.

At this point, I think that I am resigned to pulling out all my LR and dipping (or drowning) it. This will by my first real experience doing major tank work, so it is a learning experience. I'm just trying not to kill off everything in the process. I always get the impression that these tanks are super-sensitive, and screwing with them concerns me. Might as well start sometime.

If you could help me out with a dipping solution, or any tips that would make my upcoming weekend easier, it would be great. Or if you want to come up and start lecturing me on Friday, that's fine too. I'll be the one staring at my grand prize raffle ticket, rocking back and forth slowly, murmuring to myself.
 
That's cool. Pretty sure it's a Eunice sp. worm. Can you catch and save one for me so I can get it ID'd? Have you tried baiting them yet?
 
One way to get critters out of your live rock would be to get a tank, trash can, etc., build a rack to hold the rock ABOVE the water level in the tank. Use a pump and a spray bar or something similar. Pump the water into the spray bar over the rock. Leave this running for maybe a few day, a week, who knows. If anything like your little pal ventures out of his crevice, he will fall down into the water, and no longer be in the rock. Just an idea. HTH.

I agree that thing is way cool looking
 
I haven't tried baiting. Since I've had quite a few bad hitchers, I was just going to dip the rock and see what falls out. Anything good, I'll just toss back in the tank.

How long will the fish and coral be ok in a bucket with a heater and pw? I am guessing since they survived at least a trip to the lfs, that a day or two would be fine.

Any thoughts?
 
Quite awhile as long as you maintain the salinity. I wouldn't go for a single day without toping it off.
Just dipping the rock might not prompt things to leave their burrows in the rock, hence my suggestion previously. But, it may work.
 
Thanks for the heads up. I'll make sure to make a line on the water level when I start. (Or this could be the reason to finally set up a qt tank.)

The thread I was reading was using pellagrino or something like that. Basically, carbonated water. Said the things just dove out of the rock. Do you think racking the rock would work? It seems that if these things survived being shipped from the far reaches of the pacific, that holding the rock out of the water for a couple of days is going to kill more good than bad. Then I have to worry about another cycle. What do ya think?
 
I also read somewhere, I believe from Leslie the worm expert, that the carbonated or soda water would drive the worm out in a hurry. I would also think that the worm in the picture is probably longer than any one rock you have, and you may find him tunneled into more than one rock in your rock structure at the same time. As you pull the rocks apart he might be too long to hide in just one rock, and I'd think you might just find him. He may be several feet long.
