Triton CaRx Media is a professional-grade, high-purity calcium reactor medium developed to provide a stable and clean source of calcium and alkalinity for marine reef aquariums. Unlike many natural aragonite sources that can contain impurities or silts, Triton CaRx Media is selected for its extreme purity and high density. This ensures that it dissolves almost completely and consistently, preventing the clogging and silting common in traditional reactors. When used as part of the Triton Method, it provides the foundational macro-elements required for rapid coral calcification and long-term reef stability.
Triton CaRx Media is engineered for performance, offering a cleaner and more efficient alternative to standard reactor substrates.
99.9% Pure Calcium Carbonate: Boasts a near-zero phosphate ($PO_4$) leach profile, ensuring that your calcium replenishment doesn't unintentionally fuel nuisance algae.
Stable Carbonate Output: Provides a reliable and predictable release of calcium and alkalinity, making it easier to maintain the steady 7.0–8.0 dKH range required for the Triton Method.
No Silting or Clogging: The high-density granules are optimized to prevent the formation of "mud" or silt within the reactor, ensuring consistent flow and efficient $CO_2$ contact.
High Bioavailability: Dissolves almost entirely at the correct $pH$, meaning less waste and fewer maintenance intervals for your reactor equipment.
Optimized Particle Size: Specifically graded for use in high-flow reactors, such as DaStaCo systems, while remaining compatible with all standard calcium reactor brands.
| Parameter | Recommended Value |
| Recommended Reactor pH | 6.0 – 6.2 |
| Media Density | High / Professional Grade |
| Composition | ~99.9% Pure $CaCO_3$ |
| Leaching Profile | Near-Zero Phosphates & Silicates |
How do I set my reactor pH for Triton CaRx Media?
Due to its high density and purity, it is recommended to run the reactor at a slightly lower $pH$ than standard media, ideally between 6.0 and 6.2. This ensures the media dissolves efficiently to provide a high-concentration effluent.
Can I use this media without the Triton Method?
Yes. While it is a core component of the Triton Method for reactor-based systems, its high purity makes it an excellent choice for any reef keeper looking to avoid the phosphate and silicate contamination found in lower-quality media.
Does this media provide trace elements?
Because it is ultra-pure, it provides primarily Calcium and Carbonates. To achieve a complete reef solution, it should be used in combination with Triton Infusion, which provides the necessary trace elements, vitamins, and amino acids.
How often should I replace the media?
Thanks to its high density, Triton CaRx Media lasts longer than many "fluffy" natural aragonite medias. You should top up the reactor when the media level has dropped by approximately 25-30%.
Triton Infusion: The essential partner for CaRx media; it provides the trace element support needed to run the full Triton Method via a calcium reactor.
Triton ICP-OES Water Test: The only way to accurately monitor your reactor's output and fine-tune your dosing for maximum coral growth.
Triton AL99 Phosphate Remover: Ideal for managing any residual nutrients in the system, ensuring the water remains as clean as the CaRx media itself.
