I dont hear much about these filters but they sound like just the thing I have been looking for because here in melbourne australia we are in a severe drought I mean the kind of drought when 100+ year old trees are dying and permanent lakes are drying up so we are on tight water restrictions and I keep discus!!!! I have a few questions:
Does it just lower nitrates or can it keep them at 0?
Can you go months without water changes?
what kind of maintenance/care involved with them?
is it available in australia?
and how much money am I looking at for a filter for a 55g tank including shipping?
