Manganese²⁵+ is a concentrated manganese supplement for reef aquariums. It is intended for occasional correction when ICP analysis shows manganese depletion. Manganese plays a key role in zooxanthellae photosynthesis, enzyme activation, and Goniopora tissue vitality. Manganese²⁵+ contains manganese alone, without other trace metals, for precise and controlled correction of reef systems.
Each mL increases manganese by 10 µg/L (10 ppb) per 100 L (26 US gal).
Test manganese with a reliable ICP test before dosing.
Calculate dose: 1 mL per 100 L = +10 µg/L manganese 1 mL per 50 L = +20 µg/L manganese
Dose safely: Do not increase manganese by more than 10–20 µg/L per day. Add slowly into a high-flow sump or dose automatically in micro-increments. Re-test before repeating.
Example: In a 100-gallon system, 3.8 mL raises manganese by ~+10 µg/L.
All orders are fulfilled directly by the individual brands, suppliers.
