What is Coral Acclimation? Why is it Necessary?
When purchasing corals and introducing them to your home aquarium, the one step you absolutely cannot skip is "acclimation." Acclimation is the process of gradually bringing the water parameters of the shipping bag closer to those of your own aquarium. Neglecting this step exposes the corals to sudden environmental changes, causing serious damage.
Corals are even more sensitive to water quality changes than tropical fish. During transport, CO₂ accumulates in the bag, and it is not uncommon for pH to drop significantly. Additionally, depending on the season, water temperature may fluctuate during transport, creating a temperature difference of 5°C or more between the shipping bag and the tank. The specific gravity (salinity) may also differ slightly between the breeder's husbandry environment and your tank.
When these parameters change suddenly, coral cells can undergo osmotic shock, and the symbiotic zooxanthellae may leave the coral, initiating "bleaching." Although acclimation is a time-consuming process, it is the first and most important step in keeping corals healthy and long-lived.

Preparation and Checklist Before Acclimation
Before beginning acclimation, preparing and confirming several points will ensure a smooth process.
Gather Necessary Equipment
- Clean bucket (free from tank water)
- Air tubing (for drip acclimation)
- Thermometer
- Hydrometer or specific gravity meter (if available)
- Stopwatch or smartphone timer
If you're uncertain about measuring and managing specific gravity, reviewing equipment selection options in the Complete Guide to Reef Tank Specific Gravity (Salinity) Management will help put your mind at ease.
