Of course now that I got my first reef tank as I'm sure many have read my exuberant posts I'm thinking about acquiring my auxiliary tank for like if some species get sick or I choose to quarantine new ones. What is the minimum tank equipment one should have as a reserve or quarantine? does it need filters obviously. I have a G2 max system. I got spoiled from the very beginning and got all the bells and whistles. I'm wondering what actually needed to put in tank for quarantine time. should I just go by at 10 or 20 gallon tank with a simple filter and pump?
