Sulfur denitrator experiment

[Psyire]

Sorry to hear....


But to answer your question.. 1.5 gallons (containers) of LSM. With a recirculation flow rate slighly lower than yours with the Mag 2. (this is where I believe your problem lies, but that's just my opinion) If you lowered your recirculation flow I think you would get closer to where you want to be. With a high recirculation flow I think you are getting oxygen present through your entire reactor. This is somewhat proven by your zero nitrate reading once your input was cut off.

I would be tempted to swap out that Mag 2 for a ehiem 1048 or something similar. Trust me, the results of lower nitrate are quite nice, as I have corals growing again that had stops for many months. It's made me a believer... so far.
