Not everyone
needs to culture copepods. If your live rock just needs a
little boost or you have a thriving refugium but have seen less and
less of the "little white bugs" that inhabit it, just buy some 'pods
and put them into your system to boost the population - no extra
culturing is required.
ACCLIMATION PROCEDURES Essential Live
Feeds Copepods are shipped in a 4 oz. bottle at 28 ppt to 32 ppt
salinity (1.022 to 1.025) with a little bit of food (this food will not
harm your tank residents). Copepods will settle to the bottom
during shipping, so if you open the bottle and don't see any, try
shaking it up and holding it up to the light or pouring them into a
clear jar or tupperware container (NOTE - make sure there is no soap
residue on any of your culture containers - this upsets the 'pods).
You can add them directly to the tank after bringing them up to the
temperature of the water, or you can get some water from your tank, and
combine about 25% of the bottle of the copepods to this water, and
check in 15 minutes to see how they are doing. If there is going
to be an adverse reaction of the copepods, it will happen rather
quickly, so you should know. (Of
course, if there is something wrong enough with the water that it's
killing harpacticoid copepods, then there's something very amiss with
the system. These things live in highly variable environments and
can withstand rapid salinity and temperature changes.) Usually, if that first 25% make it,
then just go ahead and add all the copepods to the tank water, and
within a few weeks you will see a bloom. A bloom is easily
detected at night by shining a flashlight on the side of the tank.
If you have a voracious eater (mandarin gobies and/or seahorses), you
might want to consider setting up a culture.
