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
