Help
Hi guys,
Ive just cut this from this website:-
http://www.liveaquaria.com/general/general...eral_pagesid=59
Its a method for ridding live rock of pests.
Submerse the new rock into a bucket filled with saltwater with a specific gravity of 1.035 to 1.040 for one minute. Any invertebrates including mantis shrimp, bristle worms, and crabs will quickly evacuate from the rock and into the bucket of water.
Remove the live rock from the bucket and sort through the invertebrates in the bucket. Determine those you want to add to your system and discard unwanted pests. Bristle worms still attached to the rock can be removed with a pair of needle-nosed pliers or tweezers. This technique can be used to remove unwanted pests before or after curing your newly arrived live rock.
I would like to know if anyone has tried it and if it is likely to cause any damage to any inverts that may be on the rocks.
Otherwise, it looks like an easy way to sort the good guys from the bad guys.

Is a good idea as long as bacteria is ok with the dip .As said in the post after the dip you can sort through what you do and don't want to keep. This being the case and the critters still alive i bet the bacteria will be ok to .

Thanks Jas.
Its a pity I dont own a marine emporium with stocks of live rock, because I would feel duty bound to give it a try and report back to the Forum.

I went on holiday for 10 days came back to find my salt level reading error - I switched setting to find my sald was at 51ppt!!! After balancing the tank I noticed that all the Aptasia I had covered on my rock had gone by a few - I have hundreds!!! The maroon clowns are now fine. I was in the process of breaking down my 250L tank so only had live rock and the clowns in there!!! A good way to kill Aptasia - just make sure live rock is all you have in the tank!!

does it say anything about killing the bacteria on the rock?
The bacteria remains unaffected. The pests themselves remain alive for a period also, allowing you nthe time to sort the good from the bad.

hello all, tried this in a fashion, made up new bucket of salt water & placed lr in sea horse tank in it[was going to clean lr with soft brush],left this for about 5 min[ got visitor], went back, bristle worms hanging out of lr. removed & destroyed. cleaned & replaced lr, went to empty bucket, all sorts in it, bristle worms, small crab[did not buy this, must have come with lr], small shrimps, and others i did not recognise. this was ordinary, fresh made salt water. i therefore think that this would work even better with stronger solution of salt water,[as suggested], there was no obvious effect to lr or corals, some had even opened up in bucket by the time visitor had left. cheers, norman
