Dosing
The maker doses this by schedule rather than by a fixed potency, so the calculator cannot use it. Follow the directions below.
How it’s used
Standard 10 ml per 1000 L daily, ideally by dosing pump. If NO3 is below target halve to 5 ml/1000 L or stop; if far above target or falling too slowly double to 20 ml/1000 L. Target NO3 5-15 mg/L; test weekly.
Cautions
• Test nitrate weekly and adjust
• Methanol-free

Carbon source feeding nitrate-reducing bacteria (dual short/long-acting formula; composition unpublished); slight PO4 reduction via skimmed biofilm. maxDose = the highest dose NYOS describes (doubled dose), not an explicit cap. No NO3 reduction rate given.
