I think this depends on how much live rock you have and if you have live sand (DSB or plenum).
IMO, if you have a nice sand bed and 1+ to 2 pounds per gallon of quality live rock, you can ditch the wet / dry.
A refugium is another option that seems to be catching on too.

what do you guys think I should do i have a cpr wet dry with carbon in the drip tray and a skimmer to an external return pump.I have 90 pounds of rock in a 75g.should i lose the bioballs and make it a staight sump.I was reading above and was quetioning myself?
personally, that is exactly what i would do, remove the media(slowly) and then make it a sump, with the lr and a skimmer and a sand ed, that is all that i would use
HTH
I had my sump custom built and had it made with a removeable bio-ball chamber for that very reason. I have a refugium built on as well and am currently working on what I should do with the chamber once I remove the bio-balls. Any ideas????
Am movin on up from a 55 to a 105 gallon tank. Currently have 80 lbs of LR, will be putting 4" aragonite sand bed in tne new tank, adding a Berlin turbo skimmer, have 2 power heads that move 780 gph combined. Will be a reef tank. You think the sump?
Recently made the switch from wet/dry to sump and noticed improvements in water quality almost overnight. I'm currently in the process of doing the same in my other tank. HTH
