Gargling noise

[Timbo13]

Hi all,

This morning I converted my red sea reefer nano ATO into a refugium. The plumbing and everything works fine but there's a gargling noise I can't get rid of. I've attached a video below. It happens about once a minute. I realize to remove the micro bubbles I'll need run the pipe into the bubble trap.
Also any advice on how to quieten the noise of the water running down the pipe into the return section would be appreciated.

Thanks in advance,

Tim

try running the return pipe below the waterline in the sump

Thanks. It’s already under the water line though. You can kinda see it in this picture

I think I've worked it out. Running it straight into the bubble trap seemed to stop the air from building up in the piping.

Thanks for helping out Zatch!
