I'm about transfer my shrimp from a 20oz orb to a 2 gallon jar. Is it ok to not buy 2 bags of marine salt, and instead to just buy 1? I was also looking at the black substrate, and was wondering how much I need for a 2 gallon jar. Do you know where I can check when the items arrive, before buying? To transfer, can I slowly dip the orb into the 2 gallon jar, and let them swim out? Also, is acclimating necessary before add them to the 2 gallon jar? And do I need to wait 2 weeks before adding them? Thank you!Is it safe to pour the water that was in the orb, into the 2 gallon water?
