The absolute best way to add the copepods to your tank is as follows:
Float bag in tank for 10min to acclimate for temperature. Never dose cold pods.
Add your Copepods just after the lights in your aquarium turn off. This will allow the copepods time to find a hiding spot before being eaten by hungry fish in the aquarium. However, if you are trying to feed your saltwater fish with copepods, dose them with the lights on and watch them feast!
Turn off circulation pumps, powerheads, protein skimmers, and UV lights for 30 minutes to an hour after dosing live copepods. This will help give the copepods a chance to settle into their new home.
