Hi all. I am expecting 2-3 bags of copepods and mysis for my mandarins. Up to now I was just dumping them in the tank after lights out. But I was thinking of putting some small pieces of rock into the first chamber of my sump (the other two are for the skimmer and return pump) and dumping the copepods and mysis in there. I was thinking maybe they would have a better chance to survive and populate. Not quite a refugium but still....What do you think? Could this work with just some rock pieces and no sand?
