Need Help with Sump Design 16" section to 7" Section

[Biglurr54]

I need help with designing my sump for my 175 build that I am doing. The stand has a 34x34x27 available. I have a 30x24x17 acrylic sump. I am going to be running the triton method so I am looking for a 20g fuge area. Where I am struggling is I want to have my fuge area at 16” depth. Then I have to step down to a skimmer section with 6-7 inch depth. Because the stand is so low, I do not have room for a skimmer stand. I think that a baffle with 9-10 inches of falling water will be loud. Does anyone have any ideas on how I can have a 16” section drop to a 7 inch section without a lot of noise?

I've never seen this and it takes up a bit of space, but if you would to put an angled "lip" after the overflow baffle from the fuge so the water didn't drop straight down but flowed over this lip down to the lower section it could make it pretty quiet. But how steep angle you can get away with I have no idea about. It was just something that came to mind. :)

Haha. Funny you say that. I did that on my 60 gallon tank. That tank has a 4 inch drop. It works but it's not silent and my new design has allot more flow over a small baffle so I don't think it will work in this application.

Take a look at synergy design, the use a drain plate in the middle of deep panel

I was actually thinking of an even more angled lip. Like 30deg or something like that. A vertical baffle but with a long angled lip going from the top down to the skimmer section.
But like I said, I have no real idea about what amount of flow it will work on.

 

[Biglurr54]

I looked at they synergy but I couldn't figure out how it would work with out adjusting the plate to match the water coming into the fuge perfectly.

I was thinking... what about a bean animal overflow built into the fuge baffle?

Plate will make more flow go thru not over spillway making it quieter and handle more flow

 

[Biglurr54]

Oh. That makes sense. I like that. So in a way it throttles.

Share the flow but not restrict it
