Overview
Running a calcium reactor is one of the most cost-effective ways to keep calcium, alkalinity and magnesium topped up in a reef tank, but the process of dissolving coral skeleton media doesn't replenish every trace element your corals actually use. Coral Essentials Calcium Reactor Part 1 is formulated specifically to fill that gap, supplying the trace elements a reactor alone typically under-delivers.
It's designed to be dosed alongside Calcium Reactor Part 2 in equal parts, together covering the fuller trace element profile corals need beyond what a reactor provides on its own.
Key features
- Blend of fluoride, iodide, boron, bromide and molybdenum
- Purpose-built to complement calcium reactor systems specifically, rather than being a general-purpose trace mix
- Developed through analysis of real calcium reactor systems to identify commonly under-replenished elements
- Dosed in equal parts alongside Calcium Reactor Part 2 for a complete trace element profile
Who it's for
Reef keepers running a calcium reactor who want to close the trace element gap that reactor media alone doesn't fully cover.
Setup & tips
- Dose in equal measure alongside Calcium Reactor Part 2 for the intended balance
- Introduce gradually and monitor coral response over the following weeks
- Pair with periodic ICP testing to confirm trace elements are landing in a healthy range
- Store away from direct light and heat to preserve potency between doses
