Oh, forgot to add, that you'll probably want the reactor to be about 2/3 full with the sulphur media and 1/3 full with aragonite media to help buffer the water since the anaerobic bacteria tend to make the water acidic. If you look at my pics I have the sulphur media in the xl nextreef reactor which feeds into another smaller reactor filled with argonite media.
As far as the amount of media needed, the volume of the Sulfur reactor should be about 1% the volume of the system if the NO3 levels are below 50 mg/l or 2% in systems where the initial concentration is greater than 50 mg/l.
