Wet/Dry Filters on Reef only tank

[the barking coral]

What's the real skinny on having a wet/dry filter on your reef only tank? Should I have one?
I currently have a 100 gal tank with 200lb of live rock, protein skimmer and am operating a wet/dry as part of the sump set up. I have read that wet/dry's are "nitrate incubators". I've always had some level of nitrate reading when I test but never above 20-40.

With that much LR you don't need the wet/dry for anyting but a sump. The reason for the high nitrates would probably result from not having a DSB. Add 4 inches of sand and they will fall providing there is not an excess of nutrients in the tank.
The main filtering function of the sand bed is for nitrate reduction

I've had good luck keeping nitrates at zero with LR/DSB/refugium(with additional DSB&calupera algaes)...never really tried to maintain a system with either a sump or a wet/dry....but I do plan to expand my system to include a 30-50 gal sump that returns via sea swirls......looking at around 500-750 gph thru the sump....refugium is around 70-80 gph and gravity returns

You really don't need a wet/dry in a reef tank. It serves the same function as the LR but does it less effeciently (by adding trates). Just start slowly removing bio material out of the wet dry. Maybe 1/4 a week until it is gone. Monitor your water to make sure the tank does not have any major re-cycles. Once it is gone your Wet/dry makes a fine sump.
