Description
Quantum Aragonite A Powder 15.4kg — Largest Calcium Concentrate Powder Making 140 Litres of Solution
Coral farms and maintenance businesses mix calcium by the drum, and Quantum Aragonite A Powder 15.4kg (SKU: QA101540) is the pack for that scale. It is calcium chloride with strontium and barium and the energy component that runs through the Reef Essential range, mixed at 110 g per litre of RODI water to produce 140 L of 40,000 ppm calcium concentrate. Half a capful, 5 mL, of the solution supplied in the pack is added to each litre after the powder has fully dissolved. Dosed with Aragonite B Powder for alkalinity, it forms a home-mixed two-part system at the lowest cost per dose in the range.
Each 1 mL of solution per 100 L raises calcium by about 0.4 ppm, and strontium and barium rise in proportion. Daily dosing is set from tests against Quantum’s 405 to 440 ppm target. A 2,000 L farm system consuming 10 ppm a day needs about 500 mL of solution, so 140 L covers around nine months. Mixing this much calcium chloride generates real heat, and the manufacturer’s warning to wear protective glasses and gloves should be followed on every batch; mixing in smaller lots keeps the temperature manageable.
Usage & Application
When to Use
- Coral farms: Propagation systems in the thousands of litres with constant calcium demand.
- Very large displays: Reefs and sumps past 1,000 L that would empty smaller packs in weeks.
- Maintenance businesses: One pack supplying calcium concentrate for a round of client tanks.
- Wholesale and retail systems: Holding tanks dosing calcium daily at volume.
Preparation & Dosing Guide
- Mix in manageable lots: 110 g per litre of RODI water until dissolved, then half a capful (5 mL) of the supplied solution per litre; smaller batches stay cooler.
- Use protective equipment: Glasses and gloves, as the mixture may become hot.
- Calculate the dose: About 0.4 ppm calcium per 1 mL per 100 L; scale the daily volume to tested consumption and dose into high flow.
- Separate lines, weekly tests: Keep calcium and alkalinity dose points apart and hold 405 to 440 ppm.
