As some of you may know I was attempting to get a 240 gallon tank brand new from my area. I checked multiple places and I could either not get the tank or it was going to cost the big bucks. So, I decided to go with a 180. Anyway I currently have a Cascade 1500 Canister filter running on my 130 gallon, and I just ordered a Fluval FX5. What im getting to is this...what would be the best way to set up the 180 filteration wise using these two filters? I do not have much experience in filteration and any help would be appreciated! I just want to get the most I can out of these two filters.
