Input and Output pipes from aquarium to sump


Photo is pipe design of my aquarium and it's sump. The bellow design is what I want to do.

Input (From tank to sump, blue) bulkhead:1" BUT .........
Output (back to aquarium, pink) bulkhead: 3/4" with 3/3 pvc pipe

So water from 1 inch standpipe goes into --> a 3/4 fitting + a 3/4 valve + two 3/4 elbow and splits into two 3/4 with a tee and pure inside the sump (look at blue arrows).

Input is normally larger than output since input works by gravity potential only and output is powered by pump, while I have valves for adjustment but concern is that;

In physical theory if dimension reduces, velocity of flow increases while volume of passing remains the same!

What do you think of my design?
What will be my water input? should I change my tubes from 3/4 to 1 for input?
Should having 3/4 reduces noise as it will be working full load with less air sucking?

Thank you for your help
