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
Daily carbon dose set by measured nitrate (chart, ml per 100 L/day): mixed/fish/frag NO3>10:3, 2.5-10:2, 1-2.5:1, aim 1-2.5 ppm. SPS/ULNS: NO3>10:3, 1-10:2, 0.25-1 with PO4>0.04:2, PO4 0.02-0.04:1. Cut 50% if below target.
Cautions
• Dose every day; if days are missed, do NOT make up the missed amount, resume the current dose
• Efficient protein skimming is essential (oxygen and removal of bacterial floc)
• Do not combine with sulphur denitrators or phosphate/nitrate removers; can be the sole carbon source for carbon-based denitrators
• Acrylic containers are not suitable; keep the dosing container almost closed
• If NO3 < 1 ppm (mixed) or NO3 < 0.25 / PO4 < 0.02 (SPS/ULNS), cut the dose by 50% and test twice weekly
Sources
Chart-dosed carbon source: there is no 'raises/lowers X by Y' potency, so effects is empty by design; the dosing chart itself is manufacturer-sourced and reliable. maxDose = top of the chart (3 ml/100 L/day), not a stated hard limit. Targets: mixed reef NO3 2 / PO4 0.1; SPS dominant 0.25-0.5 / 0.01-0.02; SPS frag 1-2 / 0.08-0.12; ULNS 0/0; fish-only <10/<1 ppm.
