Hi Jeremy,
I ordered three bags of the reef flakes from you in December. When it arrived they were of course frozen solid. Does that affect the integrity of the sand if its "live". Also, I haven't opened them yet as I am still waiting for the rest of my build to come together. Is it o.k if they aren't used and still un-opened in the packaging for 2-3 months. There isn't any best by date on the bags.
Thanks!
