This one has a large filter bag with charcoal, then foam, charcoal pad, 150 bio balls, couple pieces of lace rock. The key for this filter is there is no standing water in the unit.
Current stock levels in this tank may be pushing the bio media capacity so today I am setting up another 5g container with pads & lava rock which will be fed by one of the 1000 gph pumps.
