I would argue that wet/dry is the best bacterial based filter.. the nitrate problem is from lack of maintainace (if you clean out the sludge that collects under the filter area every once in a while the NO3 doesnt build up any qicker as long as everything else stays the same) It just has a better design to get more O2 to more square inches of bio-media then any other bacterial based filter type..
