Triton Core7 in the 5L format is the bulk-sized, high-concentration solution for serious reef keepers and large-scale aquarium systems. As the most advanced foundational supplement in the hobby, Core7 is 7 times more concentrated than traditional base elements, significantly reducing the frequency of bottle swaps and the space required for dosing reservoirs. Available in both the "Base Elements" (for the Triton Method) and "Other Methods" (for standard reefing) versions, this 5L set provides a complete, balanced supply of all major, minor, and trace elements required for rapid coral growth and long-term chemical stability.
The 5L Core7 system is designed for maximum efficiency, offering a "set and forget" approach to complex reef chemistry.
Extreme Concentration: Dosing volumes are drastically lower than competing 2-part or 3-part systems, making it the most cost-effective and space-efficient way to maintain a large reef.
Complete Ionic Balance: Consolidates dozens of essential elements into four components, ensuring that your reef receives a perfectly balanced ratio of minerals without the risk of ionic drift.
Optimized Coral Growth: Delivers the high-purity carbonates, calcium, and trace elements necessary for intense SPS and LPS calcification and vibrant tissue health.
Pharmaceutical Purity: Manufactured under strict laboratory conditions to ensure the solutions are free from heavy metals, phosphates, or unwanted nutrients.
Ready for Automation: Perfect for high-capacity dosing pumps; simply hook the 5L containers directly to your pump for months of stable operation.
| Component | Essential Role |
| Bottle 1 | Magnesium + Trace Element complex |
| Bottle 2 | Calcium + Trace Element complex |
| Bottle 3a | Alkalinity / Carbonate / pH Buffer |
| Bottle 3b | Alkalinity / Carbonate / pH Buffer |
Which version should I choose: Base Elements or Other Methods?
Choose Base Elements if you follow the full Triton Method with a large algae refugium (10% of tank volume). Choose Other Methods if you use a standard sump, GFO, carbon dosing, or zeolite-based filtration.
How long will the 5L set last?
For a typical 500L (130 gal) mixed reef with moderate growth, a 5L set can last between 6 to 10 months, depending on your aquarium's daily alkalinity consumption.
Do I need to dilute the 5L containers?
No. Triton Core7 is designed to be dosed undiluted. Diluting the solution can lead to precipitation of the high-concentration minerals.
How do I adjust my dose?
The daily dose should be adjusted based on your Alkalinity (dKH) level. All four components (1, 2, 3a, 3b) must be dosed in equal amounts to maintain the correct ionic balance.
Triton ICP-OES Water Test: Essential for verifying that your bulk dosing is keeping your system within the optimal range for over 30 different elements.
Triton N-DOC Lab Test: Use this to monitor your organic nutrients (Carbon and Nitrogen) to ensure your biological filter is in balance with your mineral dosing.
Triton Refugium Light: For those using the "Base Elements" version, a high-quality light is critical for the macro-algae growth that supports this dosing system.
