I've been working to get my sump quiet, and finally finished the overflow box. Anyways, the next problem is at the PVC tubing that goes inside my filter sock. About every 6 seconds, air building up in the tube gets forced down and out of the tube, and comes up as a big bubble. Is there any way to release this air so it doesn't come out like that? I was thinking possibly drilling several holes in the PVC going into the sock like i've seen in many sump designs.

My question would be, where is all that air coming from?
That`s where I`d start, before doing any alterations at the sump.

I doubt the problem is the sump. You are describing a problem that came up a lot in my research when I first set my sump up.
Maybe a look at some of the mods that reefers use in their overflows:

I don't know if these will help but I figure they might and it is worth posting them.
Thanks for posting this, I found out why my overflow piping is so quiet even though it was a complete fluke. It is an alteration of having a short valve controlled pipe in one ouput and a taller pipe in the 2nd one with no adjustable valve (a herbie).

It seems the herbie (one tall, one short pipe with the short one being restricted by a ball/gate valve and water sitting about 2-4" above it) is the most successful noise reduction method for people who have a dual pipe overflow, HTH.
Here is my experience for what its worth.
The problem is simple and one that anyone with any type of gravity feed over flow has. It is simply not possible to safely keep a siphon from sucking air. If you put siphon low enough it doesn't suck air then you will have to have a very large reserve in the sump to handle the extra water when the power goes off. If you restrict the overflow so that its not sucking air, then what happens with it gets restricted even more, maybe because something gets clogged?
I can tell you that holes wont help, been there done that, what will end up happening is you will have lots of bubbles that sound like boiling water. I have tried putting a tee at the bottom, I tried putting a tee in the middle. The only thing that worked for me was a tee at the top in place of the 90 going into the filter sock, this only worked for my because of my long horizontal run.
The only safe way to expel air, is to have the output just an inch above the water, or less. but thats not constantly possible with a filter sock since as it clogs the water level rises. In the end the best thing I found was trying to block is much sound from the sump as possible, by putting a lid on it and then putting the pink insulation sheets around all sides and on the top.

i've actually found something that worked. in my sump, made it so one line is "taller" than the other. ultimately, only one bulkhead is needed to keep up with my pump. in the event it gets clogged, the water will rise and fall into the "backup"
Interesting can I see a pic? that might be kinda like how the T on mine worked.
You can't see the Tee on this pic, but It was at the end of the horizontal run where the 90 was, that tee was high enough to allow most of the air to escape.

You sure can run a ful siphon that is 100% silent and safe. It's called a Herbie, or a Beananimal. I use them both. Both work great, full siphons, no noise.
