Help with plumbing?

Hello, I have a 65 gallon reef. I'm about to upgrade my sump once the silicone is done drying. It has a single corner flow drain pipe, I want to split my 1" drain pipe into two so I can use a second filter sock. This was originally not possible in my tiny 10 gallon sump, but im wondering if I keep the pipe at 1" and use a 1" T fitting to split it will it create noise? Alternatively if I stuck with the 1" T fitting and dropped down to 3/4" for the 2 drains would this eliminate noise or just slow down how much water is draining from the tank? I included pictures of what I have thrown together at the moment to help visualize it.

If the pipes are under water then you should not hear noise except at start up until all the air purges

You could also use or try a wye junction/fitting as well.
