The Aqua Tech carbon is the same thing as Marineland Black Diamond, which is typically respected as one of the better carbons.
It really depends on what you want to get our of the filter. With a high fish load, you might want more bio media to prevent spikes, with very sensitive fish, sometimes you may want more carbon to keep pollutants out of the water. Not know what you have or want to do, stick a good bio media in one side of the Penguin 330, and the carbon in the other side.
Ehfisubstrat is a great bio media in the regular and the Pro versions.
