I need to start a thread on this... I've basically finished the denitrator itself, I'm ready to install it.
My test subject will be a fairly young 120g reef in my office at work. The problem is that we are doing a major renovation at our office that I am more-or-less in charge of, so I'm insanely busy... which is why I disappear from here for days at a time recently. The last time I did a build thread, the 180g from a couple years ago, I found that I couldn't satisfy people's appetite for pics and updates... I felt really bad that I couldn't update the thread like I wanted to, so I am holding off until I have time to devote to it. I'm not going to install it until I start the thread though so I can post nitrate level progress in real-time.
Anyhoo, I don't want to hijack or distract from the OP's thread, so just stay tuned!
