There's freshwater dipping of SW live rock for the purpose of removing unwanted growths/critters.

even if intended for fw? Is the live beneficial to fw aqairiums
 
"Live rock" usually means that it's been in water long enough to have the baccteria growing on it - whether it's fresh or salt water. Most people just associate it with marine set ups. It's aiding in biological filtration.

oh alright, thanks for the info :)
 
As far as buying it, the closest thing I've ever seen to fw live rock is rock that has been colonized with plants like java moss (and bacteria just as a byproduct) . There are normally many types of marine live rock which are colonized with bacteria as well as algae and sometimes corals and other inverts. And just to be sure you're clear on this (I don't mean to insult your intelligence), but the only reason to switch live rock from salt to fresh ( or vice versa) is if you WANT to kill everything on it. SW live rock is in no way beneficial to a system that is not salt water

haha, i have no intelligence on live rocks..
i ordered rocks though, and at first i thought it was just rocks. then later i looked back, and it said live rocks, for marine or fw tanks.
i was just wondering if it was safe at all. because i dont know how it could be marine or fw?
 
I don't either. The "live" component would either be acclimated to fresh water or salt (or some brackish level in between), but any significant change would kill of the live parts. If it's for either, it could possibly just be some type of base rock that used to be live rock and the seller doesn't know the difference. In that case, it could be used for fresh, but only in systems where a high pH and hardness are desired as mos of these types of rock are calcium carbonate based
