I imagine it might.
3 months .. I had no idea. I thought reeferaddict saw results sooner than that, so I'm still hoping there's hope. Seriously if I have to wait 3 months to see an effect, I'd be better off doing a 100% water change and taking this thing offline. 75ppm is WAY too high to live with. Tank looks like crap too .. I dunno. Feeling a bit bummed out about this..  I didn't realize the Midwest unit came with bacteria seeded media. I missed that. I should have used that stuff instead of the LSM then.

My results took about a month to develop and have been very consistent since. Before I did the denitrator I battled hair algae and the sort for a year and a half. The tank now runs a tidy ZERO and that even with not getting to a water change in 6 weeks now.
The sulfur does need to colonize denitrifying bacteria in an anoxic environment. To do this I ran mine on a rubbermaid of 80 ppm tank water with a slow drip rate to begin with to promote the anoxic zone and gradually ramped it up to around the 5X media volume turnover per hour as stated in Delbeek and Sprung Vol 3 and waited to see my test water nitrates drop. I noticed a drop after about 3 weeks and after a month there was no nitrates left in the test water. During that time I had gotten the main system down to a reasonable 20 - 30 ppm. It took about 6 weeks on the main tank before my nitrates really dropped, but after 2 months there were ZERO which is where it's been ever since. You need to keep an eye on the effluent rate, as I've had mine clog a couple of times and when you start up you get that wonderful rotten egg hydrogen sulfide stench, but even restarting it in the system doesn't release enough to be of concern to the inhabitants. I've seen nothing to compare to the nitrate elimination potential of this system. For the most part it's set and forget when implemented with a little research and common sense. Be patient - about all I can say is you may want to try increasing your effluent rate and see from there. I was dauted by mine at first - but it works beautifully!

 Tony, why dont you do a nice sized water change, and then run the unit out of a rubbermaid. Sounds like a good idea to me.

Have you checked the calcium level out of the 2nd stage? In theory, with the sulfer producing acid, this may be a replacement for the CO2 bottle in a calcium reactor, or a least be of some value for calcium replenishment even if the goal isn't NO3 reduction.

Not yet. Randy Holmes-Farley did this article about sulfur denitrators where he showed the chemical reactions happening and demonstrated how the calcium and alkalinity, although there will be some, won't really be a significant source for the tank. However I'm sure it's still better than having nothing.

I don't have vol3 yet. I dropped a pretty big hint to Santa though. So ... 5x media volume. I'm using a 4" reactor and my media height is approx. 8.5". So roughly PI * 2^2 * 8.5 (Pi * r^2, where r=2 because diameter is 4") = ~107 cubic inches 1 cubic inch = 16.387064 millilitres Therefore 107 * 16.387064 = approx. 1750ml 1750ml * 5 = 8750ml/hour 8750 / 60 = approx. 145 ml/min That seems pretty fast to me. Am I overlooking anything or should it really be opened up that fast? I guess that's only about 6 seconds to fill a 15ml measuring spoon. A little more than twice what I run my calcium reactors at (I run mine at 60ml/min) so I guess it's maybe not that far off. Hmmm ... interesting. Ok so the real question is how much time do I give myself to open up the reactor to that speed?
