Revamping

O.K. I'm revamping my 72 g. I've got flourite added to the gravel, and new lights, plants are coming on tuesday. I only have an Eheim 2026 canister. Do I need to maybe put a power head down towards the bottom to move the water some more? In the bowfront with the spray bar on one side and the intake on the other I get a barrell roll effect , but there are some "dead water" looking areas near the intake. I have looked at some planted tank pic's and it seems like most have more water movement at the bottom with the powerheads.

Any help appreciated.
