i hear the emp 400 is a nitrate factory.. what should i use as an alternative?

i cannot have a sump/fuge..
i have this, an excalibur protein skimmer, 70lbs LR, and 40lbs LS
if I take this filter off, what can i replace it with?

More Live Rock and a Closed Loop system for increased flow...
Then get a canister or media reactor (fluidized bed) set up for "occasionally" running carbon or phosphate media...

I have been running a Emp 400 for over 5 years, I've never seen it build any crud.?? What makes you think this is your problem? But I also have a canister filter running - 1537gph. What size tank are we talking about?
