Odd (Noisy) Overflow Question

[Briskee]

This is maddening. I finally get my gate value tuned exactly how I want it. Now the water flowing into the overflow box is noisy! I tried to increase the flow, but there's no hope. It's a lot nosier than before. Got any ideas on how to silence the water flowing into the overflow box?

I use my gate valve to silence the box.
Not sure what type overflow you use….
You have controllable DC pump?

With DC pump, I can leave overflows wide open and still silent.

Raise the water level in the overflow box if possible

Sounds like you do not have enough water in the overflow box... IE, I believe you have to close your gate valve a little to bring the water level up, so it does not cascade down, making noise.

I have a Reef Otcopus VarioS 4. It's been running on the lowest setting with no issue. But, I'd like to get more flow in the tank. I set it to 2 and there's a little hum and I can hear water falling into the water box. I guess 2 questions. How can I minimize that falling water sound in the water box. Is there a reef-safe rubber pad I can put under the return pump?

Raise the water in the overflow box is possible but I know there are some that the design does not allow this.

Silicon heat pad

Silicone heat pad- nice idea! Thank you. I'm gonna try that for my overflow. I've just got a bunch of short pieces of tubing in the box right now.

That was answering the question about rubber pad under a pump.
