How To Make Sure Media Is Compatible? Question

    I called a Fish store asking for some cycled media and they said they have some in their sump. How do I make sure that the bacteria from their tank is compatible with mine?

    If they have near similar salinities they are compatible, i.e. fw for fw, brackish for brackish or sw for sw.
