EDIT: Fixed errors in reported values. Thanks PlantedRich for pointing them out.
I have calculated that you will loose about 3.5 in of head due to your fittings at the ideal flow rate of your filter. Effectively, your filter will be pumping as if the top of the tank was 3.5 in higher than it already is.
DISCLAIMER: I am a student, not a professional engineer. I believe my calculations are correct, but may have missed details that a professional engineer would catch.
In general, smooth corners generate less head loss than sharp corners (including the branch of Tee fittings). If you can, try to incorporate sweep elbows into your design, though it will consume more space.
Seeing the amount of equipment you want to have inline, you may want to consider putting an external pump inline with your filter. This will combat your head loss.
By the way, good job with the unions. My first attempts at piping did not include them and I severely regretted it.
