I think Atari hit itright on the head. IMO
Bacteria is bacteria and will grow on ceramic tubes, bioballs or sand. A lot of filtration suggestions depend on the forum and the geographical location. When i lived in England, it was all Berlin skimmer and Ehiem filters (and i kept a good FO
tank). America seems to be all dsb
+ live rock and Aqua - C skimmers (I have the dsb
, remora coming soon!) and my attempt at a reef is coming along nicley.
However, the second set up looks great, the rock and sand combined with some nice fish and a couple corals really looks as if i reached into the ocean and picked up a piece of it! Other filters work as well, but for looks and stunning natural beauty, I would really recommend the dsb
skimmer set up!
But that is just my opinion
