I’ve been in the reef hobby for exactly two years as of today, but my first tank crashed and wasn’t able to recover, so I decided to redo it for today. It is now all up and running, finished the cycle stage, three fish in (two clownfish and a tailspot Blenny), filter is running with all the filtration I need, and I am going to be dosing the tank (idk what I’m going to dose with yet). I still have one open compartment in my sump though: the refugium. I am going to be putting Chaeto in it, hopefully growing it successfully (and using it to house copepods), but it is my first time with a refugium, so I am looking for some guidance. A couple of my main questions are: When should I add Chaeto? Will the copepods survive in a refugium with just Chaeto and light? What should I make sure to do when growing Chaeto? What should I look out for when growing Chaeto? Any other information is also greatly appreciated!
