Some answers to your questions are on the previously mentioned J&L website as follows:
Question: "Is your rock cured or uncured?"
Answer: Both. The rock arrives to our facility after being pre-cured in Fiji. During transport there is die-off causing us to re-cure the rock. Although we do not hold rock to specifically cure it occasionally near the end of the shipment there is rock left that is cured. If you require un-cured, "un-touched" rock that can be arranged by pre-booking on our next shipment.
Question: "If I buy cured rock, will there still be die off when I get it home?"
Answer: Usually, yes. There will be a certain amount of die due to the rock being out of the water while in transit from our facilities to your home. We do make every effort to package your rock to minimize this happening. We have found that people usually will see a very small nitrite spike. If you are adding only a small amount of rock to an existing system, you should have nothing to worry about.
