Where is the noise coming from?

It's the water falling from the weir teeth down to the through bulkhead level. I'm working with the manufacturer to sort it out. Currently running the back box height 1" from overflowing and still hear trickling/falling water. I'm not willing to run the back box height any higher as it won't give the emerg standpipe enough height to handle full flow.

It's not super loud, just annoying when the house is quiet. Keeps making me think something is leaking

Nice restart buddy, my box is super quiet maybe the stand pipes need to be raised or need more flow from return pump!

I tried max return flow to start with. That's when it was the noisiest.

Couldn't you just add a gate or ball valve?
You have 2 drain lines I would add a valve on one of them!kinda like the Herbie overflow
From what I've read the higher the water falls in your overflow box the noisier it gets.

I have a gate valve on the main drain, just under the tank
Problem I'm finding is, with the design of this overflow setup, the back box sits lower than the front, so the water falling through the weir teeth 'falls' down to the level of the 1-1/2" through-the-glass bulkheads. Unless you run the back box nearly full, you get water falling.

Gate valve see pic #4 on page 1
First few pics also show the difference in height between the front and back boxes

Looks good Greg, really like the cleanup process and attention to detail, very neat.

How many gph are you running to the display?
The emergency overflow pipe should be able to handle quite a bit, so i suggest bringing the water up as much as possible to the teeth, like 1/4" or even less.

On my old 120 running a Eheim 1262 full blast i had to have the main drain pipe closed about 95% with the gate valve on a 1" drain, so I don't see how a second emergency pipe can not take all the flow if something were to happen...

Looks good, get some siporax or marine pure to compensate for the lack of live rock...just a thought.

Thanks for the good thought big guy. If I ever get any Nitrates I'll consider it.
Currently Salifert tells me 0
Let's not forget that I don't have anywhere near the # of fishies you do

Crappy update ...

Bought some Lyretail Anthias and a Coral Beauty.
Put them through 4 weeks of observational QT and missed Brook
Put them in the DT and started losing the lyretails. Then the main fish started getting sick. Then we lost our fave fish Bennie the starry blennie.

Put all the remaining fish in the 36g bow and ran a round of Furan-2.
Then started Chloroquine Phosphate @ 80mg/g.
Lost both fairy wrasses.
Fish not eating.
A week later dropped the CP down to 40mg/g.
Fish eating again.
Lost the largest lyretail - again Brook - 1 left.

So, from 14 fish, we're down to 5.

Going to run the CP for a full 6 weeks, then flush it out and run them through whatever is needed next while the DT sits fallow 'till New Years (12 weeks).

I'll try to get the enthusiasm to post some coral pics some time soon ...

Built a feeder tube for the shrimps in the DT so I don't have to pollute it too much as I was getting some algae issues.
