Sulfur denitrator experiment

[Delphinus]

Sorry that this is such a long thread.

Day 14:

NO3 - 75ppm (Salifert, not going to bother with Elos until the NO2 is gone)
NO2 - 2.0 ppm (!! )

I have the flow cranked way, way back. Like 1 drop per 5 to 10 seconds.

I really do hope I'm seeing a reduction in nitrite and not just wishful thinking. Will test again in a couple of days. I figure at this point there's no benefit to testing every day, but maybe 2x or 3x a week until I see the NO3 drop.
