i go scuba diving every 3 or 4 days over the summer and i was wondering if i could get some live rock from the ocean in boston and put it in my reef tank so my questions really are

1. will the algae be too different
2. will the temp change be too different
3. would i have to leave it out of water to kill off parasites?

I've hear somewhere you can get 5 years for over a pound without a license..
I'd say just leave it and enjoy the scene

i dont think u can in mass

The live rock we get is from tropical waters. You may get a few hardy species of bacteria or algae that may tolerate the temperature change, but I'd leave it in the water. What's the point in killing the animals on the rock in conditions they aren't used to?

the temp difference will ultimateley be what does them in, plus i havent ever seen any porous rock around here, just big grey rocks, where were you thinking of taking from?

i was thinking about getting it from rockport

I tried this from out temperate California waters back in the 80s before we had good tropical LR. Was great for for a few weeks, but slowly lost everything. Bacteria and such can adapt, but not the higher life forms, so go with tropical LR.
