Correct placement of Top Filter and Power head

[csk]

I have 4ft X 1.25ft X 2 Ft tank (~66gallons). I have placed a Power head on the Left side wall and picks up water from the bottom of the Tank .
I built a DIY top Filter and the Filtered water drops right above where my Power head is placed. Is this alright or should I output the filtered water far away from where the power head is placed. I have a feeling with my current setup, the Powerhead might be pulling in the just cleaned water each time instead of pulling in unclean water

If the intake for the power head is at the bottom of the tank and the output of the DIY filter is at the top by the power had then is seems like the power head will be mixing the ouput with the rest of the system pretty well. Seems like a good objective in my book.
