Skip the Fuge part. I had this exact setup a few years ago. Attached ar ephotos of my sump. One thing to be sure to do is to keep the skimmer in an area of the sump that is CONSTANT level so that it performs consistently. this is SO essential with the modern skimmers. In this TOP photo. from Left to right we have 1. Bioballs/Rubble/drain area (removed so it was just an open void to allow bubble to escape. 2. Media area for Purien and Chemi-Pure. 3. Skimmer/Fuge area. heater was in here 4. return area with 2 extra stupid baffles they installed. I wanted them close together but they screwed up. I drilled them out to make this whole space 1. I neded up modifying the return area because it was TOO SMALL. My best advice would be to make a skimmer/FUGE area and then your return area. be sure to have an ATO installed as with my 75, they can evap up to 1 gallon/day.
