Which carbon and GFO?

[ltkenbo]

So this reactor:
Dual BRS GFO and Carbon Reactor - English

What do you think of it? I know d2mini has one in his big tank.


But which carbon and GFO should I get, there's like different types, I'm trying to tackle dinoflagellates right now so keep that in mind:

Bulk packaged carbon for aquariums - English
Bulk packaged Granular ferric oxide GFO for aquariums - English

i use the pellets for gfo and if you are using a reactor use the fine carbon get the rox i think it is what it is called.
