What to look for when buying live rock?

I'm looking at buying some live rock from a person who is taking down their tank.

I know she said it is rock from Florida, but what should I look for when if I go buy it?

Thanks,
Matt

In general, look for pests (hair algae, aiptasia anemones, majano anemones etc.) that you do not want to have to battle with. It is also a good idea to test the water for phosphates. If the phosphate levels are high, the rock will absorb it and you will likely have issues with keep your phosphate levels down once you set up the tank. In general, I prefer light porous rock that will maximize the surface area for bacteria and a generally appealing appearance.

It may sound simple but I recommend smelling the rock. If it smells rotten then I would avoid it.

Don't forget to think about how the rock shapes will fit into your planned rock structure. If you pick out unique pieces you should be able to make some cool structures.

Another thing to check for is copper. If they ever treated their fish in the tank, the rock will absorb some of the copper. This isn't too bad if you are just doing FOWLR, but will kill any corals you may want/have.

i would buy only froma trusted source and then scurbbed down let it dry for a couple of weeks and then added to your system slowly as this is the only safe way how to add live rock without having problems

Are you in the Detroit area? Do you know a good place to get good live rock reasonably? After reading these comments I am kind of shying away from buying from someone I don't know.

It depends on what you want the LR to do, what you want it for.

If you want it as a source of misc livestock, you look for LR with the best growth, and place it in a tank with medium that has been already cycled very well.

If you want LR as the medium of filtration, you can cycle from rock that has already lost most higher lives on it (cured).

Just my experience but when buying LR from LFS I have found sometimes it smells rotten which means lots of die off is occuring. Not really something you want to put in your tank and if you do you will need to scrub it and most likely kill anything living that is remaining.

The best live rock I have had experience with has that fresh ocean smell which to me is a good indicator of quality.

You don't necessarily regard dieoff as unwanted.
