So i want a Mandarin but my tank has only been set up really for two or three months! Way too early for a Mandarin. But I got a bottle of Copepods! So I am on my way! I heard you can increase your population of copepods by putting them in the refugium? Do i just through them in there. Do i need live rock down there for them to live? Wondering if i just trow them in there wont they just get sucked up by the pump? Just wondering how to get started? --dom--
