Successfully acclimating copepods to your aquarium is essential to ensure high survival rates and establish a thriving microfauna population. Though copepods are hardy, introducing them properly reduces stress and helps them become a sustainable part of your tank’s ecosystem. Here is a step-by-step guide to acclimate copepods effectively.
Why Acclimate Copepods?
Copepods are robust creatures able to tolerate varying conditions, but acclimation helps reduce stress, increases survival of important breeding females, and enhances population establishment in your tank.
Preparing for Acclimation
- Float the Container: Upon arrival, float the container or bag in your tank for about 10-15 minutes to equalize the temperature.
- Use a Drip Acclimation Method: Place copepods and their culture water in a clean container. Slowly add small amounts of aquarium water over 30 to 60 minutes, ideally diluting the original water gradually by 4 to 5 times.
- Avoid Direct Mixing: Never dump the shipping water directly into your tank without acclimation to prevent sudden changes in water chemistry stress.
Adding Copepods to the Aquarium
- Choose the Right Time: Add copepods at night when fish activity is low, minimizing predation risk.
- Turn Off Equipment: Temporarily switch off filtration, protein skimmers, and pumps for 30 to 60 minutes to prevent copepods being removed.
- Distribute Copepods Strategically: Seed both the display tank and refugium if available. Use a turkey baster or syringe to deposit copepods near rocks or substrate for better establishment.
- Restore Equipment: Resume normal filtration and water flow after 30-60 minutes to maintain water quality.
Supporting Copepods Post-Acclimation
- Feed quality live phytoplankton such as PhycoPure™ Reef Blend regularly to support copepod growth and reproduction.
- Maintain stable water parameters, moderate lighting, and sufficient habitat structures like live rock and macroalgae.

FAQs
Do copepods need acclimation?
While hardy, acclimation reduces stress and boosts survival and reproduction.
Can I add copepods directly to the tank?
Direct addition may increase stress and mortality due to sudden changes; acclimation is best.
Should I add copepods during the day or night?
Add at night to minimize predation and improve establishment.
Conclusion
By carefully acclimating your copepods and considering timing and tank conditions, you’ll maximize their survival and help build a robust population that benefits the entire aquarium ecosystem.
