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
phase : start , mlPer100L : ~0.5-1 (half of chart) , note : manufacturer: half dose to start , phase : maintenance , mlPer100L : 1-3 by NO3 level , note : forum-relayed manufacturer chart
Cautions
• Manufacturer: start at HALF the recommended dose for the aquarium type and dose daily (bacteria starve if dosing stops).
• Typical maintenance quoted 1-3 ml per 100 L/day depending on nitrate (forum-relayed chart: NO3 1-2.5 ppm -> 1 ml; 2.5-10 -> 2 ml; >10 -> 3 ml per 100 L). Verify against the bottle.
• Do not combine with sulfur-based denitrators; do not stack with DIY vodka/vinegar without reducing both.
• All carbon-dosing guardrails apply; users report it removes nitrate faster than phosphate.
pH effect: neutral (as dosed).
