Filtration for rainbow fry

I have another couple of questions about filtration for rainbow fry. Do you
need to use carbon in the filters?

I will probably use an undergravel filter because that is what I have in my
growing tank. Is aeration from the undergravel filter enough for the fry or do
you still need an air stone? If the aeration from the undergravel filter is
enough how fast should the bubbles be to run the filter and still be slow
enough as to not endanger the fry.

Thanks...
