Wish I would have seen that presentation from the last meeting
Hello, I am new here and reply because I am interested in BADESS (Biological Autotrophe Denitrification on Elemental Sulfur System)

I am interested in the sequel of this story to match with our experiences. I have been true the Koralin guidelines setting up the denitrator and I am not very happy with what I have been reading so I am curious how this worked out.
My opinion not enough sulfur may be used for a 700 gal system and reducing the level to below 1ppm would only be possible when the daily nitrate production is very low. When following the Koralin guidelines I do not see how this could be managed. Maybe a carbon based denitrator can be managed this way but certainly not a sulfur based denitrator. Hopefully I am wrong and can I learn something from your story. Using a sulfur denitrator system, it should be possible to have control over the nitrate level in the aquarium and keep it on the desired level, a big difference apposed to other nitrate reducing or removing methods who are only able to reduce nitrate, not control it.. Thanks.
