In looking at this pic, http://yadokariya.up.seesaa.net/image/snm_drop.jpg, definitely some skimming happening, why not drop the pipe from the tank into a downdraft-type skimmer (like the ETSS shown in the same pic?!?).

So do you get some protein skimming with this as well? @Tetsuo, how do you use ozone in conjunction with this? I’d worry a little bubbling it in like a counter-current protein skimmer…. But suppose you could bubble it in on the pipe from the tank….

?Muggz
Here is one DIY example for the overflow pipe.
I never used the pipe, but I heard that some people put some parts at the top of pipe to avoid falling down the live stocks.
As you can image easily, it creates a lot of noise because of the falling water to the sump.

How would you use this on inch pipe would this work with 1 inch return pvc do they sell that screwon plumbing at home depot or anything like that? That would be great if they did. I plan to build one similar but not sure how I want to attach my pvc to this. I was maybe just thinking of a slip fitting and weldon a coupler to it

@TAKA, I once thought of doing something like that, but couldn’t figure out how to solve the plumbing underneath. How do they get the return into the drain? And is it difficult to maintain something like that when there’s so little space? I assumed there’s some kind of bulkhead between the return and drain, but what happens when something gets stuck in the drain between the bulkhead and return piping? Maybe it’s not as complicated as I think it would have to be…

I could see the above overflow drain being a huge improvement for a design like that though, I imagine splashback and saltcreep would be an issue once it exits into the sump.

oh i see..Do you know why they left the bottom open? Do you know where the water level should be when placed in the sump?

It set up in the sump.

Some acrylic is on the bottom, but not entirely.

@Richard, the trap sites inside the sump, but is not built into it. The bottom is not sealed, but uses the bottom pane of the sump to “seal”.

so this bubble trap is not built into the sump but just sits in the sump? do you have any other pics of this ? Is there acrylic on the bottom of this it does not look like there is but i could be wrong.
