I really need help. (Hopefully with a Herbie style drain)

[Marlin65]

My tank makes a huge amount of noise but if I tune it just right there is no noise. I have a 1-1/2" pipe with a basket. The thing though is I have a piece of airline zapstraped to that and just adjust it up or down to make the noise stop. If for some reason the hose clogs. (I keep it at the max height I want the tank to ever be) then the water gets sucked right down fast with tons of noise alerting me that there is a problem.
Hope that makes sense.
Maybe a small piece of hose is all you need.

Another idea would be to install a Tee directly below the bulkhead and run the branch line up and then down into another section in the sump. Next install a valve just above the sump on the main drain line. Closing the valve will cause the drain to fill with water stopping air from entering the sump. You'll want to adjust the valve so water just starts to trickle out the other drain and the back up the valve a tiny bit. This will work similar to a herbie overflow but only needs one drain, it won't be as quiet as you'll get noise through the second drain line as it's connected to the main but you should be able to muffle it.

Great idea I would try this on mine but I don't have enough room for that now.

sounds like you have a 90 going into the sump ... can you remove the 90 and replace it with a T ? this will help reduce the back pressure allowing the top of the T to act as an overflow. This is only a temp. solution until you get the time to plumb it better.
If you want to slow down the flow you should use a ball valve on your sump line as well.
