How to silence an overflow?

I can't view the video right now. I'm assuming you have just the stand-pipe(s) and not an overflow wall/baffle to deal with? The weir on the overflow may also by the bottleneck if you had one.
Running 50% on a pump is all relative, it may be sufficient for your set-up. some other reasons why it's making a lot of noise is your primary drain isn't below the water enough and sucking in too much air. Do you have a gate valve or equivalent on your drain to control the flow? 1" restricted, and, running at full siphon can take on a lot of water.
I didn't see the King's video, but from the still shots, I think it would also be good to add a strainer to the primary drain to avoid larger things getting stuck.

So the sucking noise could actually be from not running enough flow? I am getting a gargling out of the stand pipe and a sucking noise out of the actual overflow. I am running a speedwave dc 790 on my 75 gallon so I would like to be able to run it at least 3/4 to hopefully get a true turn over rate of somwhere around 5-6x's per hour.
Correct. But you didn't answer any of my questions
. You do have an overflow box? How far below the water line is your primary drain? That can definitely the reason why. If you provide more specific information we can narrow down.
I see, thanks. I would say that OP would want to make sure the drain is under the water level enough to create a full siphon. In my experience, even with 1" you still may need a gate valve to fine tune to avoid water swooshing later down in the pipes.
