Hi all,
All aerobic is definitely a winner for me.
A lot of discussion on the more expensive filter media relates to them potentially supporting both aerobic and anaerobic within varying sized pores. I can't see any point to this, all it means is that a small increase in your bioload will cause all the filter media to become de-oxygenated, with catastrophic results.
Have a look at "Greg's Peas" posts in this thread <Alfagrog for reducing Nitrates? | UK Aquatic Plant Society>.

Pretty much in terms of biological filtration, if you look on a lot of marine forums they've gone away from wet and dry trickle filters because they are "nitrate factories". All this really means is that because these filters have a huge gas exchange surface, and the filter media remains aerobic, you can deal with a huge bioload.are you essentially saying then that oxygen is the limiting factor in the growth of all the beneficial organisms in the tank?
