even if u order cured LR online u will still have to cure it when it gets home.
Not all together true. I ordered some LR
and it did not need to be re-cured. If shipped over-night with and in-transit time of less then 20hrs there should be little die off on the rock. They claim it is safe to add directly to the main and I experienced no NH3
spike when doing so. It really depends on where you get the rock from. My recommendation is liverocks.com.
