I've heard this referred to a few times.....but not sure if I want to do it. My measly 20 lbs of live rock is infested with predatory crabs. I've removed 3 (they were dead, not sure if they're being killed by the others) and there are at least 3 more plus one very loud pistol or mantis shrimp. Before I add any fish to this tank I need to get these crabs out. Ive heard that a FW dip will do the trick but I want to make sure I'm not going to damage the rest of the LR too badly, and also how long I would need to keep the rock in there. Or, for that matter, is there a better way???
