ReMag Magnesium Media – 1 kg – Two Little Fishies

Product details

ReMag Magnesium Media – 1 kg – Two Little Fishies is a magnesium-rich aragonite media designed for use in calcium reactors in marine reef aquariums. It replenishes magnesium and carbonate alkalinity as part of a calcium reactor setup, helping support the ongoing demand from corals and coralline algae that build their skeletons from calcium carbonate. Used together with Two Little Fishies ReBorn (or other calcium reactor aragonite media), ReMag gradually contributes magnesium carbonate to the reactor’s effluent, supporting stable reef water parameters in long-term operation.

Features:

• Magnesium carbonate–rich granules formulated for calcium reactor use
• Gradually replenishes magnesium and carbonate alkalinity during calcium reactor operation
• Supports reef aquariums where maintaining magnesium and alkalinity is an ongoing need
• Coarse granule size supports water flow and CO2 diffusion for reactor efficiency
• Does not add chloride or sulfate ions that can disturb ionic balance
• Can be used as directed inside a calcium reactor to help maintain magnesium concentration

Specifications:

• Product type: Magnesium-rich calcium reactor filter media (granules)
• Net weight: 1 kg
• Primary composition: Magnesium carbonate and calcium magnesium carbonate
• Recommended mixing ratio (with ReBorn): 1 part ReMag to 9 parts ReBorn (as referenced by the supplier guidance)
• Granule size: Approximately 5–10 mm
• Reactor mixing limit (as referenced): Do not exceed 25% ReMag by volume to avoid raising alkalinity too high
• Solubility note (as referenced): Soluble at pH 6.5; slightly soluble at typical aquarium pH values
