I had about 16lbs of
LR in my 10g with about a 3.5-4" sand bed. I also had a
DIY refugium that hung on the back of the tank. I ran it with a Maxi Jet 600 powerhead. In the first chamber of the fuge, I had a small
CC skimmer and a 100w heater. I also had two MJ400's in the tank for circulation. I used
NO lighting at first and then upgraded to a 2x36w
PC that was also
DIY. It worked out well although it required daily top offs (as most any tank does) to keep the water level up and I did weekly 20% water changes.
