monteray is prittly clean because it is a marine santuary. rmpd109 is right, the farther out the better. if your tanks sycled then adding crabs should be ok, although ive been diving out there and its hard to find anything that isn't huge. right now im setting up a large cold water tank and im hoping to go diving for sand and live rock in a cupple of months, so if in a cupple of months you want some more message me. oh, you should also get a bait lisence if you want to colect sand, i think you can get them at outdoor world cheep. if you want to collect crabs get a fishing lisence
