## Questions & Answers

**Q: how long can you keep this sand in bag before it kills the sand**
A: 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.

**Q: what is special grade?**
A: 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

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

**Q: Can it be used for fresh water**
A: 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.
