Closed Loop Heat / Noise?

[coreytrv]

Hello, couple questions on large build est. 700 gallons. 120" x 32 wide x 48" tall

Planning on locating it in the living room. Fish room a ways away in garage. Common sump / tied to filter on another tank.

I plan to do closed loop under the cabinet. Maybe Abyzz, or some other big pump.

Question:
Is noise a consideration by having the pumps in a cabinet in the house?
What about heat? Will I need to plan for vents? (if I vent it, sound will also get out)

One of the first things I consider when picking a pump, ( return, closed loop, circulation), is it quiet?
I've found out the hard way, one person's quiet, can be another's noise nightmare.

DC pumps seem to have changed all that.

My RD3 pump bodies run cool. The controllers are warm and I keep them outside of the cabinet.

Dc pumps for closed loops are way more quiet than the old iwakis and don't add as much heat to the water either.
A lot of them have various modes which eliminates the need for anything like scwd adapters

Thanks for the response. Definitely looking at DC pumps here. If Abyzz A400, we are looking at 200 watts at 50% output.

The pump won't be submerged, so I'm more thinking about the heat generated within the cabinet air space, and if that should be vented.

Regarding the noise, rubber feet, and possible soundproofing the cabinet?

Just a suggestion......
You can get 3 x Red Dragon 5 ECO 200W pumps 3500gph ($1200) for the same price as 1 A400 https://www.royalexclusiv.com/Flow-...0-Watt-13-0m-3500-GAL-HIGHPRESSURE::1015.html

I have 2 Abyzz A200's running my closed loop. They are under the tank with some other electrical components, sitting on a wood platform. My sump is remote. I run them at 50-90% and have had no issues with heat or noise. They are virtually silent and so far bulletproof. As for heat, the stand cabinet shares airspace with the canopy cabinet and I have an exhaust fan in the canopy so there is some air circulation. With that the stand area stays essentially room temperature while the canopy runs pretty hot with all the lights.

I have Vectra L2’s in a tank in my living room and they are silent. I hear the water movement from the tank more than I hear them

I plan on wrapping the stand and canopy but noise from the closed loop is definitely not an issue. I have the water pointed towards the surface with RFGs and the turbulence on the surface is louder than any of the water flowing through the sump or closed loops.

I wouldn't be concerned about venting for heat even in the cabinent but based on the closed loop pump choice, how large of a system is this and where is the sump located? I would vent/have some large dehumidifier to prevent mold/mildew issues if the tank+sump are potentially that large to justify using an a400 imo.

Very nice setup, like the aluminum stand. Piping is clean! :beaming-face-with-smiling-eyes:

Remote sump 30' away in garage to maximize display area. Only thing under the stand will be the closed loop piping, and access to overflow plumbing.

To @danreef55 's point, I could see a number of scenarios where that math's out. However in this tank, where I will be chasing flow for SPS 30x. I need more powerful pumps.

The Abyzz A400 is almost 2x as powerful as the Red Dragon 5 200w. With only (4) bulkheads for closed loop circulation I need to get as much flow as I can for each hole.

(2) A 400's can give me almost 10,000 gph, wheres the Red Dragons will only give me 5,000 gph.

Here's a rendering of the proposed tank.

having lived with an 82x32Wx30H mixed reef tank for 10 years, if I had to do it over again, the one thing i would absolutely change is the width and possibly the height. once corals grow in, the 32" is tight and the 30" is tall. i should have gone 36" wide which would likely have made the 30" height easier to work with
your design makes for an amazing picture window into the ocean but consider how you plan to scape and stock it. 48" tall and 32' wide is going to be tough to maintain.

 

[danreef55]

Your rendering is awesome!
As Reef_ranch stated consider reducing the height. You only have a limited amount of space to service the tank from above. The maintenance becomes much more difficult at 48". Actually, the recommend 30" would make thing far easier for you in the long run

 

[coreytrv]

@reef_ranch I agree on the width, I wish I could go wider, but I will start encroaching into a window if I go any wider...I'm pushing to get 34.5, but once you figure 1-3/4" acrylic, I'm back down to 32.

@danreef55 you are both probably right on the height...I may need to bring it down a little, if for no other reason than to avoid having to do a barrel roll off a ladder to get in! :grinning-squinting-face:

The above said, would it change your perspective if I told you I already created a service nightmare for myself on a 72" tall tank, lol

Then you know EXACTLY what I am referring to!!!
You tank looks great congrats
