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
Normal stocking: 1 drop per 100 L daily, adjusted to consumption; the older regimen of 1 ml per 200 L weekly is still allowed. Pause when corals respond with stronger color. KZ's own tanks: 0.5-1 drop/100 L once or twice a week.
Cautions
• Stop dosing when corals show color increase
• Overdosing can turn yellow Acropora greenish (guide)
Sources
Korallen-Zucht publishes only a dose regimen (shop pages DE/EN, ZEOvit Guide Easy Reefing 2018, Product Finder dosage schedule 2013); no ppm/mg-per-ml potency and no composition figures are published anywhere checked (KZ states no SDS is required, so none exists). Effects left empty. Frequency conflict: shop page says 1 drop/100 L daily; 2018 guide says 1 drop/100 L twice a week. EN page gives the old regimen as '1 ml/wk/50g' (i.e. ~200 L).
