Overflow suggestions

[Rayzzfish]

I've had this aquarium for seven years and never had a problem all of a sudden the overflow is leaking and its noise. I'm looking for suggestions to fix it. I've add a couple of photos to show it. Thanks for the help.

I think you need more/better pics and a video with sound (upload to YouTube and link it). People could guess the problem with the info you provided but that’s it.

I assume you’ve checked everything is still tight and there are no cracks or damage?

I saw your avatar and couldn't help but think. . . Rescue that poor discus from the ocean!

On a more serious note, more picture would help. Also, are you sure the leak is coming from the overflow/bulkhead?
