Premium Calcium Reactor Media - Aragonite

Maintain stable calcium and alkalinity with our professional calcium reactor media . Two Little Fishies ReBorn pure aragonite for calcium, carbonate, and trace element reconstitution.

ReBorn Media Available

  • ReBorn Coarse Media : Standard particle size for main reactor
  • Little ReBorn Media Fin : Fine particle size for post-reactor pH adjustment
  • Pure aragonite : Fossil skeletons of reef-building corals
  • Complete dissolution : No residue or impurities
  • Optimal CO2 consumption : Maximum efficiency

ReBorn Media Crude - Main Reactor

  • Standard particle size for calcium reactor
  • Replenishes calcium and alkalinity
  • Releases strontium and trace elements
  • Controlled and predictable dissolution
  • Size 8.8 lbs (4 kg)
  • Duration several months depending on the speed

Little ReBorn Media End - Post-Reactor

  • Fine particle size for pH adjustment
  • Ideal for secondary reactor
  • Effluent pH rise before aquarium
  • Fast and effective dissolution
  • Consumes less CO2
  • Size 8.8 lbs (4 kg)

Composition and Purity

  • 100% Pure Aragonite : Fossilized Coral Skeletons
  • Calcium carbonate : natural CaCO3
  • Strontium : Naturally present
  • Trace elements : Magnesium, boron, iodine
  • Phosphate-free : No contamination
  • Silicate-free : No unwanted algae

ReBorn Media Benefits

  • Complete dissolution without residue
  • Optimal CO2 efficiency
  • Guaranteed purity, free from contaminants
  • Complete parameter reconstruction
  • Extended lifespan
  • Excellent value for money

Calcium Reactor Operation

  • CO2 injected into reactor chamber
  • Lowers pH to dissolve aragonite
  • Releases calcium and carbonate
  • Enriched effluent returns to aquarium
  • Maintains stable settings automatically

Reactor Configuration

  • Fill room with ReBorn media
  • Adjust effluent flow rate (drops/minute)
  • Adjust CO2 injection for pH 6.5-6.8
  • Test calcium and alkalinity regularly
  • Adjust according to aquarium consumption

Target Parameters

  • Calcium : 400-450 ppm
  • Alkalinity : 8-10 dKH
  • Magnesium : 1250-1350 ppm
  • Effluent pH : 6.5-6.8 in reactor
  • Aquarium pH : 8.1-8.4 stable

When to Use a Calcium Reactor?

  • SPS Aquariums : High Calcium Consumption
  • LPS Aquariums : Hard Coral Growth
  • Large volumes : 200+ gallons recommended
  • Automation : Maintaining parameters without manual dosing
  • Stability : Avoids daily fluctuations

Maintenance and Replacement

  • Check media levels monthly
  • Replace when 50% dissolved
  • Rinse chamber during replacement
  • Clean the circulation pump
  • Check CO2 bubbles regularly
  • Test the effluent periodically

Media Lifespan

  • Depends on effluent flow rate and reactor pH
  • Generally 3-6 months for 8.8 lbs
  • SPS aquariums consume more quickly
  • Monitor the level visually
  • Replace before completely depleted

Alternatives to the Calcium Reactor

  • Two-part assay : Calcium and alkalinity separated
  • Kalkwasser : Lime water for top-off
  • All-in-one : Combined solutions
  • Reactor = better long-term stability
