im looking into setting up a qt tank soon whilst my aquareef 400 is cycling.
I also have a 130l freshwater tank running that I was going to get rid of but thought I could use it as my qt tank as it's an AIO.
As the freshwater tank is already cycled, would I be able to just empty the tank and fill with saltwater but still use the filter media which is already in there?
