I have my QT up and going. 20 gal long with emporer 400 filter (no biowheels just filter floss) with seachem matrix that was seeded in my DT sump. I have a HOB seaclone skimmer, heater, and themometer. No sand or live rock. I am trying to get 30" lights for the tank. Do I need to have a CUC in the QT? Is there anything I'm missing? Just doesn't seem like enough filter to me.
