Noisy drain Aqua One Mini Reef 120

Postby kiwis » Sun 24 Jun, 2018 7:56 pm

So I've recently got a Aqua One Mini Reef system (120L), link at the bottom. The system seems to work very well however the overflow drain is ridiculously noisy. Like I can hear falling water right now in another room.

The water flows through into the weir and down into the drain as per this picture (1 is down, 4 is return). It's falling into the sump and I believe this is where the noise is coming from. The sump is filled to the specified level.

Can I please have some advise on how to quieten this system.

I reduced most of the noise by extendingthe return pipe under the water level.

Send me a PM and I can email you a pic of what i did.

As mentioned above, extending the overflow pipe below the waterline is said to help a lot with the noise

How did you go with the drain noise? Give this a try if you’re still having issues.
