Would it be alright to put in LR w/o washing to start the cycle?

Since your going to ship it anyway and are starting out a new tank I would go for the uncurred live rock and place that into your tank to help start your cycle.. Normally un-curred live rock goes a little cheaper as well..

And to answer the rest of your question.. Yes to all.

as long as you're willing to deal w/ whatever hatches out of it...

I would give it a quick rinse if I were you. I didnt rinse mine and I regret it because all the rubble that fell off into my nice sand.

When I started my tank my local reef store advised me to clean the LR by taking a toothbrush (new) and giving a quick clean to get off the sponges and loose rubble from the exterior of the rock. The purpose was that since this typically represented dead matter by removing it you could speed up your cycle. If you rinse, I would use tank water not tap or RO - you can keep it as alive as possible IMO. You'll find there are as many views possible and you need to choose what you believe to be the sensible way forward. Hope that helps.

wouldnt rinsing the rock kille the life off of it? or ar you supposed to rinse in salt water only?

I guess I'm pretty much alone in this subject.

I've always gotten cured liverock (never ordered livestock online though I guess...).

No matter how careful you are, your "cured" liverock will always have enough die-offs to start the cycle, and I've never had to wait longer than a week for the cycling process to finish.

When I was in high school, I worked at a petstore, and just for fun, I tested our un-cured liverock tanks from the moment it arrived, and took about 3 months for the cycle to be completely finished.

Now I'm sure there are far more liverock per gallon than any home aquarium, but the 3 months cycling time isn't just for one cycle. The tank went through about 4 separate cycles.

By separate cycles, I mean every time when ammonia is almost down to 0, it would spike right back up. I probably contribute that to the amount of ammonia that is there in the first place, killing things that WERE living.

I can't imagine that long of a cycling time for a home aquarium with uncured rocks, but why do you want so much nitrification bacteria to begin with when in reality after the cycle is done, you won't have nearly as much bio-load to feed the bacteria and have them die off?

Nitrification bacteria can double in population in a matter of 24 hours, when's the last time you doubled your livestock?

Oh, and plus, uncured liverock really stinks.
