Acrylic External BeanAnimal Overflow Box

These ended up not working

I am taking the external box off today and going back to the Glass Holes design. Unfortunately the height difference between the teeth internally and the height of the box externally creates a waterfall affect instead of the intended bean animal design

I have raised the height as high as I can on the external box but still cannot submerse the bulkheads with water causing a large splashing sound inside the internal Glass Holes box because the water level ends up so low... I think the only way this would have worked is to make the box as tall as the trim of the tank and shim the difference of the trim the rest of the way down the box.

 

here is a video of it in action

 

I added the Glass Holes baffle and a thing of mesh to the internal box which seems to have quieted that side down but I still think the external side is louder then intended... Here is a better video with audio on youtube.

 

Bud sounded pretty bad lol. (Ok not funny). By the end he could only push out about half of the letters of his words.
We tried many different deflectors in both boxes. It would make one side better but not the other. The flow coming through the 2 1/2" bulkheads is just to violent.
It's of my opinion that the bulkheads need to be totally submersed. Is there a way to cut out the side with the holes and just make the changes there?
Mine is going on a different tank (120g ) so now I would like the holes a little higher. I can get you the height... Could it be more like this? Maybe with a 1/4" glued to the lower section.

Ok sounds good. The 2 tanks might be the same not sure. But I just measured the current holes from the top down on my 120g. So from the "Top" of the trim on the DT to the "Center" of the GH bulkheads is 4 3/8".

I just mailed mine off you will get it tmw.

If you need any dimensions from me let me know but mine needs to be the same as the other holes offset by the 2" trim of a 180g tank.

 

I have a loud calcium reactor and the scrubber makes a little noise but the rest of the tank is very quiet now

 

Very cool!
