Plumbing Help

So I have a 180, with a synergy reef cl44 sump. Two Vectra M2’s. Did a leak check and I'm getting a ton of noise from the internal overflow and in the sump area. I've made a video to help explain. A local store advised me to vent the primary and secondary drain. Basically put a T in the horizontal run of each drain and run a vent tube up above the waterline. Looking for suggestions before my wife makes me sell this thing, lol. Please see the video, and let me know if you can’t view it. Thanks in Advance, (update- Synergy reef advised me to bring up the water level in the overflow, without the gate. So i cut a new drain pipe and this raised the water level in the internal box. Helped a tiny bit. Also they stated after the system runs and builds up some bacteria slime it will help to make the system more quite)

what happens if you raise the flow of water and let the emergency drain have a trickle of water go so? Great video quality.

If raising the flow doesn't work, set the flow back like it was and turn off one of your vectras and see how that works.

If i raise the water it gets a bit more noise

I did that and the flow through the sump seems a bit more quite but the overflow is still noise

Turn off one of the vectra. They are very powerful. I was shocked you had 2 on your 180. I have the exact same vectra but I only have 1 on my 210 lol. Try turning one completely off. That over flow is only rated for about 2500 gph the vectra are 2k
but you have 2 so you are pushing more water than the overflow like. Try it and let me kn ow.

Assure the pipe in the overflow is submerged under water. If not get a union with an extension to make that happen

I have the eshopps overflow and I just set up a 75g and it was making the same noise, I turned down the pump and problem solved. I cant hear it now. I think Deezill is right you have too much water being pumped in.

Still get Noise

Turn off one of those powerful vectras , if that works then use the off vectra as a backup.

Unfortunately a pretty standard side effect of the Shadow overflows if you attempt to put any serious flow through them. There are quite a few threads on here about the issue along with the salt creep it causes... the only real solution is to either raise your main siphon and secondary dangerously close to the edge of the box AND cut your flow under 900ish GPH, or replace your overflow box with a modified version Modular Marine makes specifically for this issue. The noise itself comes from the weir where the water drops a significant amount into the height of the external overflow box (For some reason they decided to make them different heights) You could also add some coarse filter sponge inside the weir and that will help but you'll need to change it frequently to keep the weir from clogging...
