Dead Rock okay to use?

[Reefer Rob]

After what they've been through to get to your tank, the critters on "live rock" are tough! Unless your dead rock is real grungy I wouldn't worry about it. You don't have any fish or inverts in yet do you?

no fish or inverts yet so I threw it in a bucket of SW with some aeration and it still has some pink/purple stuff. Could that still be alive? I got this stuff used but I believe it's been dry for atleast a year.

Just make sure you use some live rock to seed the rest of the rock
