Overflow box noise

[lemmy_k]

What are you people doing to quiet the water noise of the overflow box? I tried bio balls foam and a riser tube. Foam seems to do the best job, but I'm afraid of the nitrate levels rising if I don't clean it everyday or so.

Is there a way to make a Durso for a HOB overflow?

[Etunes]

Wow, thanks i was gonna make a thread with this exact same question. Isnt this just a siphon method?

[CaptainAhab]

Yes and Yes... It's in the overflow. That was the topic. If you're also adding in sump noise then there are options to deal with that also but I was just answering the overflow.

Although not made for HOB people have done it.

Tried it in my HOB sometime ago, could never get it right so I ripped it out. If anyone has pics/vid of someone making it work post them please

Can a Durso Standpipes work in a hang-on the back overflow?

Here ya go...simple yet totally effective.



It's just a plastic cup with a hole in the top and an airline coming out of the hole. It sits over the HOB drain. Totally silent...and cheap.

and that cup stays put huh? very nice

[ccCapt]

Yep. You can see a small piece of eggcrate on the left. The cup is wedged between the eggcrate and side of the overflow to keep it from moving.
