Landolakes,
Does the water from the tank feed into the HOB Refugium and from there back to the tank?
I have an under the tank sump, but want to refugium for pod production and also to help keep nitrates down. If I put the refugium in the sump the pods will get sucked up through a pump and be dead by the time they hit the tank.
Also, is the lighting for your tank enough for the refugium too?
My lighting is all open and about 12" off the top of the tank.
Thank You!
