Quantum Mineral Sea Salt 20kg Box — Bulk Natural Sea Salt Enriched for Reef Aquariums and Spa Use
A 20 kg box of natural sea salt with reef-grade minerals is a different proposition from a box of synthetic mix, and Quantum Mineral Sea Salt 20kg Box (SKU: QA052000) is aimed at keepers who have decided they want the former. The Reef Essential Mineral Oasis blend is an authentic sea salt with raised minerals, enhanced buffering and added major, minor and trace elements, packed in a box for large reef systems, mixing stations and anyone using it in quantity for baths and spas as well as the tank.
Quantum supplies the detailed method for each application on the insert inside the pack, and it should be followed for whichever use you have. For a reef, mixing is the same as any salt: dissolve the weighed amount in RODI water, mix until clear, let the temperature settle and confirm the specific gravity before the water goes anywhere near livestock. For a bath, the manufacturer’s sensitive-skin rate is about half a cup, roughly 125 g, per standard 150 L bath, with its chart for stronger soaks. The only caution printed is not to overdose, and with a box this size the salt should be resealed after every use.
Usage & Application
When to Use
- Large reef systems: Displays and sumps of several hundred litres on a weekly change schedule.
- Mixing barrels: One box feeding a reservoir that serves more than one reef.
- Spas and frequent baths: Bulk quantity for households or businesses using mineral salt regularly.
- Trace-element supply by salt: Systems where the keeper relies on water changes to replace minor and trace elements.
Mixing & Application Guide
- Start with the insert: The pack insert holds Quantum’s full method for aquarium, bath and spa use.
- Aquarium mixing: Add salt to RODI water at around 25 °C, circulate until fully dissolved, allow the temperature to stabilise and verify gravity.
- Bath use: Around 125 g per 150 L bath for sensitive skin; the pack’s chart covers stronger doses.
- Reseal and measure: Close the inner pack after each use and never exceed the recommended amount.
