Welcome to Canreef Fresh
IYWMO, to me 100lbs of live rock can't be too much rock, 3 or 4 buckets tops. Why not get some steel covered gloves
and give each rock a saline dip in hopes that you catch it sooner than later. Just be sure to dip for less than a minute or so for each piece in water of a salinity at around 1.040, otherwise you will have a bunch of dead rock instead of live. I did this when first starting out, and it helped me catch a little pistol shrimp which I though was a Mantis
, either way that little shrimp sure took a nice piece of flesh off my finger
, which is why I suggested the steel golves
