how long can you keep this sand in bag before it kills the sand

Usually every bag comes with an expiration date , I assume the live bacteria will stay alive till that time keeping it at room temperature, when I placed my order of sand, mine had a expiration date for more than a year . So I'm sure they send you fresh packed sand. I completely recommend it.

what is special grade?

The title is confusing on this item as "Special Grade Reef" and "Fiji Pink" are two totally different types of sand. Both are nice but the Special Grade is a bit bigger, if you go to there website you can see the differencehttp://caribsea.com/pages_caribsea/page_product_aragalive.html

My ammonia didn't spike at all. live rock is in, did your ammonia spike with this sand?

This is supposed to cycle your tank instantly... if you have an ammonia spike then you need more live rock. The bacteria in this acts as a filter

Can it be used for fresh water

You can use this for freshwater but it will kill the bacteria, but the sand would be fine to use. the one drawback though is it is aragonite sand, so a lower ph it could dissolve some and add too much calcium in your water. For saltwater you actually want some calcium to dissolve for the corals, but i don't think extra calcium would hurt anything in freshwater.
