Overview
Part 3: Magnesium is the magnesium component of East Coast Corals' three-part dosing system, supporting the calcium and alkalinity balance that's central to healthy coral growth.
Magnesium acts as a buffer that helps calcium and alkalinity stay in balance — if it drops too low, it becomes much harder to keep those other two parameters stable, even with careful dosing.
Key features
- Concentrated magnesium solution designed to complement Part 1 and Part 2
- Helps maintain the calcium/alkalinity balance central to stony coral growth
- Liquid format for straightforward, precise dosing
Who it's for
Reef tanks running a three-part dosing regime, particularly those with stony corals where magnesium tends to get overlooked relative to calcium and alkalinity.
Setup & tips
- Test magnesium periodically — it's often the forgotten parameter behind stubborn calcium/alkalinity swings
- Dose consistently rather than only when levels drop noticeably low
- Use alongside Part 1 and Part 2 as a complete system rather than in isolation
- Keep dosing containers clearly labelled to avoid mixing up parts
