Dead Rock okay to use?

yup....use it up..

Im setting my new tank up with 90% dead rock. It was my old LR that I had no way of keeping wet for a few months. Im going to get a HUGE cycle from it but eventually it will be LR again.

Just watch your water parameters after adding it. You should get some kind of spike.

So if I just add it my parameters will go up right? Would it be so high that it will kill off live organisms already on the live rock? It's been 2 weeks and my tank has yet to show any type of cycle with 40lbs LR with lots or critters and coraline.
Should I put it in heated buckets with aeration for awhile first?

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?

[Carmen]

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
