You would have to cut the flow way down to do that.
The DIY denitrator use a very slow rate of flow to operate properly if I am correct.

Ya, I think your right Midknight. The water needs to be in there long enough that the oxygen is depleted and the anaerobic bacteria process takes over.

Now I was thinking of "T"ing off of the return on mine to run it through a denitrator.

Now that would be cool - and I don't see why it wouldn't work.

Sorry I know this is an old post but I am curently having a nitrate problem and a detrius problem. So I just bought a fluval 305 to hook up to my 350 gallon system so that I can remove the detrius more eaily and efficiantly. I think you just have to be dedicated on rinsing your sponges.

most run them without sponges actually in regards to a reef tank, that is when they are not being used for mechanical filtration. Such is/was the case with fish's tank.
