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
1 ml per 100 L daily, for very nutrient-poor tanks with pale corals lacking depth of color. KZ doses it for 5-10 days when needed, then returns to regular Xtra once colors recover.
Cautions
• Not for brown or creamy corals - use regular Xtra (guide)

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.
