double.. grrr

Thanks Darren!
That's good info.
I am curious why you call the old design a single pass?
the recirc pump constantly circulates the water through the media so would it not be called a multi pass?
Thanks

I am calling it that because in all other designs out there water either flows from the bottom up. Or the top down. Or even swirls it around. I guess I should have called it a dual flow. ;) Symantics..

Ahhh yes now I understand what your talking about. :)
Dual flow makes sence.

That is how I will be running mine. But How I will be doing it is that I have an overflow box and bulkhead that until I have the sump set up will be used to take water from the tank into the skimmer. That is where I will be dripping the effluent. So that it passes through the skimmer to aid in removing any CO2 and as well mixing to adjust pH and such to match the tank as closely as possible.

In your case... All I can suggest is that if you were to do it try splitting the return into two or possibly three outlets. Then take each "branch" and have it drip over top of a powerhead or area of high flow so it is mixed quickly. Very quickly.

That is pretty much all I can suggest.

Anyone else?

Tony (delphinius) has his drawing from the tank and dripping into his overflow pipe into his sump. I suppose that's very similar to how you kinda have it set up Darren.
I wouldnt suspect one would have to worry about the effluent too much. If your water movement is good it should be dispersed quite efficiently through out the tank.

DJ do you have any pics of this reactor now that it is running?

He has posted this thread over at reefcentral.com as well...there are pics there of the unit working
