I have a 120 gallon tank with a 12" Arowana, 10" Albino Oscar, 10" Red Bay Snook, 7" Tiger Shovelnose, 13" Snowflake eel, 8" Lung fish, 8" Clown Knife fish, 12" Black Ghost Knife, 10" Albino channel cat, 2 Jack Dempseys, firemouth, Green Terror, False Jaguar cat, and a 6" Brown knife. As you know this is a lot of meesy fish for this tank. I currently have 2 Emp 400's. This weekend I am going to look for a good canister. Does anyone have any Ideas on Which is the best one? I would like to change my water change routine from once a week to at least once a month.

If you can wait, the new XP4 is coming out and also the FX 5 is aout now, that one moves alot of water.
Your filtration method has absolutely NOTHING to do with your water change amounts.
Filters break down fish waste into Nitrates.
Water changes removes the Nitrates.
Better filtration will not substitute for water changes. Keep changing, or remove some fish.

Ok I will still do the water changes, but I also asked what would be a good canister that would lower the nitrates.
Filters don't lower Nitrates, they produce them.. unless you have a de-nitrification filter which is pretty much un-heard of for hobbyist aquariums. That was the point of my first post.. 
Rena XP3 is a good canister filter.
I will also soon be getting a 55 gallon to move the cichlids into. In my 120 I would like to have just the clown knife, the shovelnose, the lungfish, the arowana and a red tailed cat.
Damn, that's a lot of fish for that tank. I have one 18" silver aro in a planted 125g w/ 2 e400's and it gets nasty if I don't vacuum the gravel at least every other week.
How much water are you changing? I vacuum out about 30g when I do a water change.
BTW, live plants will help break down nitrates so you can stretch you water change intervals.
