New Wet/Dry filter questions

[Paintbug]

well i finally got my wet dry filter today. but now after reading about using bio-balls and them causing the nitrates(correct?) to stay high in a LR/coral tank im thinking i will not be using them. is it difficult to just make the wet/dry a fuge? what would be involved. right now i have not even put water in the tank so i am trying to get the game plan set first. i am also planning on having a deep sand bed as well, LR and all the other will come as well. i really need some pointers on this filter so i dont have to set something else up after i have water in the tank. i have a 75 gal and will be using a HOT overflow with the wet/dry.

that answered a couple of questions. im leaning toward placing a HOT fuge on the back of the wet/dry. i have seen it done, but im still trying to figure out exactly how its plumbed.
