Calcium²⁰+ is a concentrated calcium supplement formulated for reef aquariums. It is intended for maintaining and correcting calcium levels that fall below the natural seawater range (400–450 ppm). Unlike blended maintenance formulas, Calcium²⁰+ provides calcium alone, making it ideal for safely raising levels without disturbing balance.

Directions / Mode d’emploi

DIRECTIONS

Calculate the dose from current and target calcium. 1 mL per 25 L (≈6.6 US gal) raises calcium by approximately 6.06 ppm. Dose slowly into strong flow. Do not raise calcium by more than 20 ppm in 24 hours. Measure in 0.1 mL increments and retest after 24 hours.

WARNINGS

Never mix concentrates. Separate from alkalinity additions by at least 10 minutes. Avoid eye and skin contact.

For aquarium use only. Do not ingest. Avoid contact with eyes and skin. Wash hands after handling. Keep out of reach of children.

MODE D’EMPLOI

Calculer la dose selon le calcium actuel et la cible. 1 mL par 25 L (≈6,6 gal US) augmente le calcium d’environ 6,06 ppm. Ajouter lentement dans un courant fort. Ne pas augmenter le calcium de plus de 20 ppm en 24 heures. Mesurer par incréments de 0,1 mL et refaire le test après 24 heures.
