Need help Silencing New Waterbox Infinia Reef 230.6

[Soup Sandwich]

Hello there,

I just sent this message to Waterbox, but it turns out their help desk is only available Monday-Thursday and I am trying to get my cycle started this weekend, so I wanted to reach out here to hopefully get some answers.

I am in the process of water testing my new Infinia Reef 230.6 - I am having an issue silencing the system.

I have adjusted the gate valve to have the water level in the overflow box just slightly below the emergency drain. However, no matter what level I have the water at, the overflow weir is flowing water directly into the emergency drain, which is causing a lot of noise. Aside from the noise, it does not seem right to me that the weir should flow into the emergency drain, as the emergency drain should remain dry and clean, and only carry water in case of an emergency. Have I missed something in setup, or is there an issue with this design? The height of the emergency drain is ~1/2 an inch below the horizontal supply, so it can not be plumbed any higher.

A few additional questions:

In setting the tank water level - I filled the display tank just to the bottom of the overflow weir, and then filled the sump up to about 2" below the top so that during a power outage the sump will not over flow. Is this the appropriate way to measure how much water should be in the system? Is there a recommended sump water height for when the system is turned off?
I purchased the Syncra SDC 9.0 with this setup. Is there a recommended flow rate for this return pump on this system?
**Additional note - the system was flowing water from the weir into the emergency drain even when I had the return pump tuned down to 20% (~400gph)
Is there a recommended water height for the return chamber of the sump during normal operation?
Is there a recommended water height for the display tank?

Any help would be greatly appreciated!

Thank you

Bump. Let's see if we can get you some help.

Could you post some pictures?

Thank you for trying to help out! I tried getting a picture - but due to the horizontal plumbing, it is a bit challenging to show exactly what is going on. The attached picture is a top down view of the overflow box. Circled in red is the emergency drain, which the weir is flowing water directly into.

I did wind up getting a response from Waterbox today, and they mentioned that I would likely need to turn down my return pump to reduce the amount of water in the display tank, thus reducing the amount of water going through the weir. However, even down to 15% flow rate of the Syncra SDC 9.0, I am still getting water into the emergency drain. Which means I need to drop it down to 10% flow rate to avoid this issue.

10% of this pump when accounting for head-loss is ~200GPH, which is not even a 1x cycle rate for the tank, so I do not see this as an appropriate option as I would prefer to have at least 2x, if not higher.

I think that my only option will be to cut the emergency drain back and add 45 degree fittings to relocate the emergency opening to the back of the over flow box. Not what I was hoping I would have to do with a new $5,000 setup!

Please report back after you've made the e-drain modification! I'm looking to pull the trigger on a WaterBox and have seen this complaint pop up before. Sounds like poor design.

Can you post a video for us to possibly help? My Waterbox is completely silent and I have a very high turnover rate running through it.

Haven't been able to get a video yet - It's near impossible to show due to the supply plumbing covering the view of the emergency drain.

What model Waterbox do you have? In the picture below you can see the emergency drain to the left - this is where the water is flowing directly into from the weir if the return pump is set anywhere above 10%. I can get the system completely silent when I tune the gate valve and drop the flow way down to 10% - but I am trying to avoid that.

The below picture shows the overflow box, with the front panel/weirs removed.

Even if I apply pressure and pull the emergency drain back towards the rear of the tank, it will eliminate the problem because the water coming in from the weir won't reach the drain.

Yes, exact same overflow setup. I was hoping to see a video of the flow and where your water level was in the tank and overflow box. If that makes sense.

That makes perfect sense! I have the emergency drain removed from the overflow box to see about a modification, so I won't be able to run it until it is back together.

The water was just about half way up the weir when it was operational though, and the water level was just over an inch down from the top of the tank.

Do you know what your return pump is putting out for GPH?

Latest response from Waterbox below. Looks like I will have to go with my plan of modifying the emergency drain with 45 degree fittings to get it away from the weir and prevent water flowing through in normal operation. Very disappointing, mostly in principal only since it is an easy fix, but disappointing nonetheless when considering the high price tag.

I had this issue on my peninsula 6025. The flow through the weir would go directly into the emergency drain since it’s too close. The emergency drain was too low, so if you did the right level, you would hear the waterfall.

I just cut the emergency drain and added elbows and raised it up.

Keep in mind the dang thing is in metric. You can’t just go to Home Depot or Lowes and get stuff that fit.

Unplug it, works every time.

Otherwise, hope you find the quiet spot.

 

[Soup Sandwich]

Lol yes! Lesson learned about the metric. I plan to do the same fix - just ordered the 40MM to 1.25” conversion from BRS.

Thank you for your input!

I did this mod on my overflow today and got the elbows from Lowes. I did not have to cut pipe. Just unscrewed the outflows pushed the emergency overflow to the side, attached the elbows, put back the outflow nozles and it's now silent. Easy enough.

Hey I was looking into getting this tank also, but I keep seeing this issue pop up. Was curious do you have a video of ur tank? So I can see where I would need water level to be to be completely silent? Also what equipment are u running in ur sump.

I have maxspect gyre pumps so was worried about having this issue.

Hey there,

I was able to get this worked out for the most part. Every few weeks I can hear a little bit of water running, but when that happens I adjust the gate valve either open or close the literal smallest amount possible and that silences it.

I did have to modify the main drain with 2 45 degree elbows so that the overflow wasn't flowing directly into it.

From the top of the display glass to the top of the water line on my setup there is just over 1" of space. When I open the gate valve slightly this gap increases by ~.25" but never much more than that.

From the top of the sump to the water line in the return chamber of the sump, there is 4 1/8" of space.

I do not run socks in my sump, but I did have to put a small piece of blue matala mat in the sump area where the water first overflows into where the socks would go. This overflow was turbulent and causing a bit of noise, which the matala mat silenced. In my sump I have a Red Sea 300 Skimmer, some rubble/media, heaters, and the Syncra SDC 9.0 return pump set to 50%.

In my display I run two Ecotech MP40's - one on each end pointed inwards. I do not have any experience with Gyre pumps, but I would assume that with everything dialed in, you could adjust the return pump to keep everything silent.
