I am connecting an fx5 to a 180. The bulkhead for the intake is 6 inches from the bottom. I know canisters are meant to work with a syphon. After I connect to the bulkhead do I need to make the plumbing go up to the top of the tank and u turn before going to the filter? That way it still uses a syphon. Could I just go straight to the filter or would the pressure on the filter be too much? The output for the filter is a bulkhead 6 inches from the top if that makes a difference. Thanks.
