New Tank - a few questions

[kb90]

I am still open to what I should put in it.

I was thinking a couple clowns and some inverts, and softies and sps for corals.

To be honest I don't know much about fuge's, need to do some research. I was hoping with the AIO tank I could get away with too many major mods.

How about filter media, I am not able to find what the original 3 were. So currently I have carbon and Poly, and ideas what that last one would have been?
