The Triton Core7 Bulk Edition is the high-capacity, ultra-concentrated dosing solution designed for large-scale reef systems and high-demand coral aquariums. This 4-part system is 7 times more concentrated than traditional base elements, allowing you to maintain stable water chemistry with significantly lower daily dosing volumes. By moving to the 5L bulk format, reef keepers reduce plastic waste, save on cost-per-liter, and decrease the frequency of reservoir refills. Available in both Base Elements (for the Triton Method) and Other Methods versions, it provides the full spectrum of major, minor, and trace elements required for professional reef management.
The Bulk Edition is engineered to streamline the maintenance of complex reef chemistry without compromising on lab-grade precision.
7x Concentration Advantage: Drastically reduces the storage space needed for dosing containers and makes it the most efficient solution for high-growth SPS reefs.
Complete Ionic Stability: Consolidates essential minerals into four components, preventing the ionic drift and chemical imbalances common in multi-part dosing.
Lab-Grade Purity: Every batch is manufactured under strict laboratory conditions, ensuring it is free from contaminants like heavy metals, phosphates, and nitrates.
Simplified Management: All four parts are dosed in equal amounts, making it easy to automate with a 4-head dosing pump for hands-off stability.
Cost-Effective Bulk Format: The 5L set offers the best value for aquarists managing systems over 500 liters (130 gallons) or tanks with high calcification rates.
| 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 bulk version do I need: Base Elements or Other Methods? If you have a large algae refugium (10% of tank volume) and follow the Triton Method, choose Base Elements. If you use traditional filtration like GFO, carbon, or protein skimming alone, choose Other Methods.
How long will a 5L Bulk Set last? On an average 500L (130 gal) mixed reef, a 5L set can last roughly 6 to 10 months, making it a highly sustainable choice for long-term maintenance.
Should I dilute the 5L solutions? No. Core7 is formulated to be dosed undiluted. Dilution can cause high-concentration minerals to precipitate out of the solution, potentially clogging dosing lines.
How do I dial in my dose? Start by measuring your daily Alkalinity (dKH) consumption. Use the Triton Dose Calculator to find your starting point, and adjust all four parts equally to maintain your target dKH.
Triton ICP-OES Water Test: The essential tool to monitor the performance of your bulk dosing and fine-tune trace element levels.
Triton N-DOC Lab Test: Recommended for bulk users to monitor organic carbon and nitrogen, ensuring biological balance alongside mineral dosing.
Triton AL99 Phosphate Remover: A high-capacity media that pairs perfectly with bulk dosing to keep nutrient levels in check.
