I am use to using HOB
filters I just recently put a sump on my 60 reef it does not have the refug. Will start a new thread to discus that. Any way piont is I am not familiar with sump systems.
Do I have to have a light on the refug. If so what kind is recommended. I dont have anything growing there at the moment. It came with sand and live rock in it..
Should this be changed out or what do I do with it.
