| Well, we actually need a couple of bits of info first.
What do you plan to do with it, (meanig what are you gonna keep in it) ? If its just fish, the wet dry will be fine, and you wont NEED live rock, but might want to consider it to use for decorations. If its corals you want to keep, either soft or hard, you will need to probably modify the wet/dry a little (if this is possible, may need to take it back like wit said) in order to keep the corals. I will just give you the brief explanation for now, to save space, time, and my fingers....
Bacteria is what allows us to keep marine organisms in our tanks. This bacteria converts the waste from the animals from harmful compounds like ammonia, and nitrite, to nitrate, and then breaks them down even further into less harmful elements. It goes like this...Fish give off ammonia. ammonia eating bacteria use the ammonia to live and give off nitrite as waste. Nitrite eating bacteria use the nitrate, and give off nitrate. Heres the fun part....the bio media that comes w/ wet dry filters is an ideal place for those two types of bacteria to grow...which will cause your tank to be what we call a nitrate factory. Nitrates a low concentrations are alright, but at the higher levels that you will get using the wet/dry filter as it is configured right out of the box will be lethal to corals. Why don't you tell us what kind of wet/dry you've got, (post pic if you can) and we can help you out alittle more.
