Is there any difference? I've got search overload I think . . . :-?

A wet/dry system has parts that are moist and can be colonized by nitrifying bacteria, but also come in contact with oxygen in the air. A wet/dry system can be set up in a sump, but can also be elsewhere. For example there are canister filters that incorporate a wet/dry system. The bio-wheel on some power filters is a kind of wet/dry system that is not in a sump, and has no refugium associated with it.

A sump is a water reservoir below the main tank that is fed through overflows. A sump can serve many purposes, some of which are filtration, housing of heaters and chillers, use as refugium, set up of wet/dry systems, housing of buffers like crushed coral and peat, and so on. A great resource about sumps is here. The sump of my 240G contains neither a wet dry system, nor is it used as refugium.

A refugium is an area separated from the main tank to contain the same water but prevent predation by the inhabitants of the main tank on the inhabitants of the refugium. A sump can be used as refugium, but a refugium can also be created by using a tank divider. Refugiums can house many things, some of which are plants, fry, invertebrates, and so on. Refugiums are particularly popular with salt water tanks. A breeding box floating in a tank would be a refugium that is not in a sump, and has no wet/dry system associated with it.

I was thinking of setting up a wet/dry filter in a sump which would flow into a refugium with miracle mud and plants then flow over to a return area back to a tank. Im Planning on ordering a 75 gallon acrylic tank next week to give my Haps and peacocks a new home.
Would this be practical?

A wet dry filter in a sump is certainly doable - many people use such setups. A refugium with plants is also doable, but far fewer people use such a system, because it's a lot of work to set up and maintain, and the benefits are marginal.

The whole thing sounds like a very elaborate setup for filtering a 75G, which is just a medium sized tank. For my 75G, I use an Eheim 2217 and I have some low light plants in the actual tank, which are perfectly compatible with haps and peacocks. The system works very well.

In short, what you are proposing can certainly be done, but there are ways to achieve the same results with less effort.
