Im doing a 40g hex stretch SW reef im starting to peice all my equipment together. i wonder if for this tank a sump/refugium is necessary/recommended i want it to be the best i can make it and make sure its going to be good from the start. also can i do a sump/refugium w/o drilling my tank? is their an overflow that can hang or can i maybe use a second pump to pump the water into it? i should also add that i have a Red Sea Prizm Pro Protein Skimmer that i was going to use for my filtration and a rio 1100 pump and i do have a Emperor 400 power filter but i wasnt going to use this. it came with the tank.
thanks
