I have a 180g with an fx6, a 2262 and an ac110, 20 or so juvie fish in it for now. You could consider the 2260 or 2262 in place of the fx6. The eheims are quieter and will likely last longer, though more $$. I keep the 110 for running floss and if I need to add carbon etc. The tank is still new less than 2 months since setup and for now I am running the sponge, purigen then floss in the 110.
