Overview
Part 2: Calcium Chloride is the calcium component of East Coast Corals' three-part dosing system, replenishing the calcium that stony corals and coralline algae draw down as they build their skeletons.
Calcium and alkalinity are closely linked, so keeping calcium topped up alongside Part 1 and Part 3 helps maintain the stable chemistry corals need to grow well.
Key features
- Concentrated calcium chloride solution for reef calcium supplementation
- Formulated to work in balance with Part 1 (alkalinity) and Part 3 (magnesium)
- Liquid format suited to manual or pump-based daily dosing
Who it's for
Reef tanks with stony corals or coralline algae driving ongoing calcium demand — from nano setups to larger, well-stocked systems.
Setup & tips
- Test calcium regularly and adjust dosing based on results rather than guesswork
- Dose separately from Part 1 (never mix concentrated solutions directly) to avoid precipitation
- Keep magnesium in check too — low magnesium makes it harder to maintain stable calcium and alkalinity
- Small, frequent doses are gentler on tank stability than large infrequent ones
