Should this hole be in my return line?

[GothFishKeeper]

I just finally finished setting up my 65g and turned the pump on for the first time. I noticed the flow seemed really loud so I looked in the corner-flow section where the noise was coming from. It turns out that there’s a hole on the underside of the elbow that my loc line is connected to, and it’s spitting water against the plastic and back into the overflow instead of out my loc line into the tank. The pvc pipes in the corner flow section came with the tank and each pipe assembly came already put together. Is that hole supposed to be there? If not, what can I do about it?

Yes it’s supposed to be there. I think water level is too low if you hear it. I took a piece of sponge filter pad and zip tied it on so water can still come out when needed but it doesn’t splash

These holes are often on return plumbing to act as an anti-siphon device when your pumps turn off. If your tank has these, they may be needed to prevent sump overflow-don’t block them unless you are sure your sump can handle the resulting siphon when your pumps go off. If noisy you can do as VintageReefer suggested and either adjust the water level in your overflow or position a piece of filter sponge to prevent splashing/noise at the water surface.

Thank you guys so much for the helpful responses, it’s good to know I don’t have to completely tear down my plumbing to replace that pipe lol
I would definitely raise the water level in my overflow to avoid the splashing noise but I don’t think that’s an option on my tank unfortunately so I’ll be getting the smallest piece of black sponge I can find at work today

Obtain a zip tie. Rubber bands will crack in time

There is no way to raise the emergency line? Pipe connector or new pipe?
