It depends on your priorities. Core7 Flex 4-Part is recommended for best results — highest concentration, best trace element stability, and separate calcium/magnesium control. Core7 Flex 2-Part is simpler — fewer dosing pumps, easier to monitor, with known trade-offs in long-term stability. TRITON Balling is for reefers who prefer the traditional Balling method — TRITON provides ICP-tested salts and adding Infusion gives you the full TRITON Method. CaRx with TRITON media is for established calcium reactor users — lowest long-term running cost, but requires CO₂ setup and reactor management experience. All four paths are ICP-guided and all connect to the TRITON Method through TRITON Infusion.

Both are high-concentration dosing platforms available in 4-Part, 3-Part, or 2-Part format. Both share the same kit structure (A, 1b, B, 2×C, D). The difference is component 1b. In Base Elements, 1b contains the macroelement and traceelement solution plus TRITON Infusion — a proprietary trace element blend. In Reef Supplements, 1b contains the macroelement and traceelement solution only, without Infusion. Choose Base Elements if you run the full TRITON Method with a refugium and macroalgae filtration. Choose Reef Supplements if you run a different approach — Balling, carbon dosing, calcium reactor, or regular water changes.

Yes — 2-Part is an officially supported configuration. It requires fewer dosing pumps and is simpler to monitor. TRITON recommends 4-Part for best results because it provides better long-term trace element stability and allows calcium and magnesium to be adjusted independently. But 2-Part is a valid option, especially for smaller or less demanding tanks. Starting dose for 2-Part is 4 ml per 100 litres.

After your ICP-OES results arrive, your MyTRITON dashboard provides personalised dosing recommendations.

Starting doses: 4-Part and 3-Part: 2 ml per 100 L of tank volume per day. 2-Part: 4 ml per 100 L per day.

Target alkalinity: Build toward approximately 7 dKH — an optimal level for most reef systems, where corals calcify efficiently and trace element consumption remains predictable.

Initial adjustment phase: Test your alkalinity (dKH) daily and adjust dosing accordingly:

• If alkalinity rises, reduce dosage by 10–20%
• If alkalinity drops, increase dosage by 10–20%

Continue fine-tuning until alkalinity stabilises around 7 dKH.

Once stable: Test every 3 days to monitor for any required adjustments.

Ongoing monitoring: After the initial setup, re-test with ICP after 2–3 weeks to evaluate system response. Adjust dosing as needed, then move to ICP testing every 2–3 months once the system is stable.

TRITON Infusion is a proprietary blend of trace elements and other beneficial substances. It is the chemical component that helps define the TRITON Method and supports the refugium and filtration framework efficiently enough to eliminate the need for water changes when used as part of the full system. It also serves as the connecting element across all four TRITON dosing paths.

Core7 Flex Base Elements already include Infusion in Component 1b. However, Infusion is also available as a standalone product — allowing reef keepers using Core7 Reef Supplements, Balling, or a calcium reactor to add it separately and achieve full TRITON Method trace element coverage.

Infusion transforms any dosing approach into the TRITON Method.

Yes. TRITON produces its own ICP-tested Balling salts (NaHCO₃ for alkalinity, CaCl₂ for calcium). Mix them following the TRITON Balling instructions, then add TRITON Infusion to the calcium solution. Your Balling setup now delivers the full trace element coverage of the TRITON Method. Magnesium, potassium, and other elements are added individually based on your ICP-OES test results — only what your reef actually needs.

TRITON CaRx media is 99.9% pure calcium carbonate — the purest reactor medium available. Near zero PO₄ leach eliminates unwanted phosphate introduction, which is a common problem with lesser-grade reactor media. No unwanted contaminants and very low leftover after use, reducing pipe blockage. Combined with TRITON Infusion dosed separately, your calcium reactor becomes part of the TRITON Method.

Yes. A number of public aquariums use this approach because it provides full control over pH stability.

Core7 delivers a higher pH solution, while a calcium reactor produces a lower pH output.

We recommend starting with a 50/50 ratio and then adjusting to achieve your desired pH level.

Two-part dosing maintains calcium and alkalinity — two essential parameters. Core7 Flex goes further. It supplies calcium, alkalinity, magnesium, and all essential trace elements — including the proprietary TRITON Infusion blend — in one integrated system. Combined with ICP-OES testing, it monitors 45 parameters (not just two) and provides personalised dosing guidance. Both approaches can keep corals alive. Core7 Flex is designed to help them thrive.

Core7 Flex Powder is a concentrated powder format that you mix with RO/DI water at home. Each kit contains labelled bags (A, B, C, D) and liquid bottles (1b).

Solution 1: Mix the powder from Bag A + Bag D with 1× Liquid 1B into approximately 1 L of RO/DI water, then top up to a total volume of 4 L. Mix well to create a 4 L ionic solution.

Solution 2: Mix the powder from Bag B into approximately 1 L of RO/DI water, then top up to a total volume of 4 L. Mix well to create a 4 L calcium ionic solution.

Solution 3a & 3b: Mix the powder from Bag C into approximately 1 L of RO/DI water, then top up to a total volume of 4 L. Mix well to create a 4 L alkalinity (dKH) solution.

For established TRITON Method users, a TRITON ICP-OES analysis every 2–3 months is recommended. The standardised system keeps parameters stable between tests. New setups, recently changed dosing amounts, or tanks experiencing problems benefit from more frequent testing — monthly until the system is stable. Between ICP tests, monitoring alkalinity with a home test kit is useful to track daily consumption. The target alkalinity for Core7 Flex is approximately 7 dKH.
