None of the fancy stuff, no carbon, definately none of the stuff that removes any of the ammonia, nitrites etc.
I assume it will take a cartidge. Most of them come with carbon, this is okay if you don't want to mess with modifying other stuff to fit. I did finally look it up and should have known. The filter has 2 biowheels. These are your biological filtration, they convert ammonia to nitrites and nitrites to nitrates as well as other surfaces in the tnak and the filter. To start out, if you do not have fish and are using ammonia to cycle then you do not need to add anything else. The cartridges can be added when you add fish.
I am actually getting an Emp 500 I think and I will not be using the cartridges. I am going to modify sponges that are meant for Aqua Clear filters or whatever else I can find that will fit. I hate wasting money on cartirdges and I don't use carbon so for me, the sponges and other media will work best.
So to answer your question:
If you are cycling with fish or food, then you need the cartridges.
If you are cycling with pure ammonia then you do not need to add them yet.
I hope that makes it a little clearer. Let us know if it doesn't. And don't worry about asking questions. Rather have to answer a few extra questions than not get things right and have the fish suffering.
