not completely true. as far as pods go, the copepods we see in our tanks never really exceed a millimeter. the larger pods are adult amphipods or isopods. basic rule of thumb is that IF it is a pod and you have to squint to make out features, it's a copepod. point is, they're quite different; not just different life stages.

that said, there are a LOT of "tiny white things." a better pic or a good description might help.
