New to the hobby, 75gal tank with a 20 long sump
You have 2 issues.
1- for the overflow going to you sump you should make a Dorso standpipe (very easy to do and will remove the gurgling sound you hear.
2- your sump is rising in level because your return pump is not able to push the water back to the DT as quick as it is coming in.
This can be caused by 2 issues.
1- the water flow through your sump is not fast enough
2- your return pump isn't big enough.
Do you have your pump turned all the way up? Also what is the diameter of the pipe for your return? What is the height from your return in the DT to you return pump?
Check the main page off reef central for head loss calculator. Input the data and it will give you what size pump you need.
I have a 1320 gph return pump plumped into a 1" return and it was only capable of keeping up with a 1" drain at full siphon so you 1200 seems low for a 1.5" drain.
Here is a pic of my Dorso. Google it, it's very easy to make.
Please note that my caps are not on the top of my standpipe in that picture.

Capsle, my return is 3/4" all the way up to my bulk head my bulk head coming through the tank is 1/2" with a 1/2" 90 threaded on with a 1/2"-3/4" bushing. I'm not sure on the height I will check when I get off work and as far as my return pump being turn up all the way I'm not sure, I really didn't see any adjustments on it but I will look again

I forget the name of it again I'll have to look when I get home after work, sorry I'll get the name of the pump and the height
The reduction you have on your overflow plumbing is't helping with the sound, also never a good idea to reduce down a overflow pipe, you are asking for trouble there IMO. 1" is safe for about 700gal/hr max, but I alway suggest to go bigger.
I would do as suggested above, build a durso and install an overflow box. this may require you draining 1/4- 1/2 the water out of the tank for a few days, but both the durso and overflow will help with sound immensely.
Those screw on grate style overflows can clog up pretty quick with algae, esp during your cycle when algae blooms are common, this can lead to you coming home to a flood or in worst case scenario a house fire caused by said flood if power stips or sockets get wet and start arcing.
Hope this helps.
For a newcommer though, nice looking setup! good job. wish more people made youtube vids to get help diagnosing problems, makes it much easier to give beneficial advice.

My bulk head is an 1.5" and I had to reduce it to 1" BC that was the size pipe coming out of my sock it but there is only 1'6" of 1" pipe being used the rest of it is 1.5" and can I just drill a hole in the top of my 90? Or do I have to plumb a T in? And thank you I have done a lot of research before doing this project and I wanted to have a nice set up with good equipment
The length of the smaller reduced piping does not matter that reduction is a potential problem. throttling back the pump via valve might help prevent problems, but catastrophic failure wise I am eyeing that (grate style) overflow as a likely potential problem, low light fish only setups, they work okay, bust still should be cleaned regularly, but a heavily lit reef they will clog with a quickness in a algae bloom.
Im not sure I follow on "drill a hole in my 90" replumb job maybe in order if you want a nice, quiet hassle free setup.
Just my .02

I know what your talking about and yes you can drill a hole in the 90" but make sure that it is sealed tight before you start the water flow and I would suggest if you can a ridged tube be placed in it because if the tube ever goes below the water line you will make a nice little siphon right where your wall outlet looks to be. When it comes to the reducer I would personally cut that 1in for the sock to make it a 1 1/2in and place the tube into the water so that its not splashing into the water in the sock. I would suggest a 90" over the sock's now larger hole with a barb and a short 1 1/2 flex tube to make changing the sock easier. I have basically your system but my 75 is a RR tank but those changes should fix the water rising issues and the noise. Otherwise nice tank and welcome to the reefing community!
So if I made my drain all 1 1/2 it will get rid of the noise? I also drilled a hole in the 90 and placed a little valve but I don't notice a difference. And my 1" tube from my sock is all the way in the water

Okay so your 1.5" overflow under full siphon with give you approximately 1300gph of flow.
Your pump can provide a maximum of 1200 gph, that does not take in to account your head loss. Also the fact that you're going 3/4" to 1/2" into the bulkhead also reduces the amount of flow big time.
You might be better off using you. Return line as your overflow and adapting it to fit you 1" socks.
If you don't want to do that you will need to replace your return pump to something that can provide you probably around 2000 gph that you can adjust.

You can continue to use a reduced size but I would then add a ball valve which you can close a bit to reduce flow and noise. That valve if fully open should work fine BTW. Here is my sump just recorded and posted for you at midnight. Why...because I have kids and they are asleep so this is the only chance I have.
