Tigger-Pods can be poured directly into your refugium and/or main tank. When dosing your display, we recommend that you add the pods after lights out so that they can settle into the rock and substrate before being consumed by predatory fish. Turn off all pumps, add the copepods and wait 30 minutes before returning your system to normal function. Since some of the copepods will cling to the side of the bottle after pouring, make sure to rinse the remainders out with clean saltwater so that you get every animal. When adding to a refugium, just pour them whether the light is on or not.
