Is it overkill

[Richardwm]

So I originally bought a c220 canister filter for my 55 gal but today I decided to pick up a magnum 350 to supplement is this to much flow for a planted tank. Also FYI to everyone with a little ingenuity I made it into a recycling gravel vac. Anyways beyond the tangent also got my 48" bml light 6300k I plan to run it for 6 hr but I have current marine orbit light that I ramp up and down base on time is this going to cause anyprob I run co2 injection and dose frets.
