From one of the most trusted names in reef additives comes the perfect pairing for calcium reactor users!


KZ's Aragonite Reactor CaRx Media is a coarse grain aragonite media designed for use in calcium carbonate reactors. Aragonite Reactor media is a very pure source of calcium and carbonate alkalinity and is free of harmful by-products. One of the main advantages of using this type of media is that it only adds necessary elements to the tank and won't increase salinity over time due to extra sodium and chloride ions being introduced as with 2-part solutions. Using a high quality reactor media like KZ Aragonite Reactor media increases ease of use and system stability. 


Aragonite Reactor media has a perfect grain size for optimal surface area while avoiding compacting that can impede flow-through. A great supplement is the addition of approx. 10% ZEOmag Magnesium Granulate mixed in with the Aragonite Reactor media.

  • Perfect for use on its own or with ZEOvit system & other KZ additives.
  • Works in any Calcium Reactor
  • Ideal granule size
  • Maintains stable calcium & alkalinty


Available in Two Sizes

  • 1 kg
  • 4 kg

Product Questions

How much volume does each 4kg bag of media use up in a reactor chamber? I don't need specifics just a rough estimate as my calcium reactor doesn't have a measurement in weight for media.
Question by: Ramsey Carskadon on Mar 20, 2022, 4:08 AM
Hey Ramsey! The amount accumlated in the reactor is completely dependent on the reactor volume itself. You can always by extra!
