Protozoa will be very small. Even on medium power they can still look quite tiny in your microscope field.
Algae will be quite small, but usually larger than protozoa
They will have a greenish or yellowish tint.
Insect Larvae are larger than protozans. Larger ones will fill your microscope field on medium power. Sometimes they have six little legs.
Daphnia are larger than protozoa or algae. They are easily mistaken
For insect larvae (but they don’t have the six little legs)
The flat and round worms are quite a bit bigger.
A planarian may fill your microscope field, even on low power, and nematodes vary in size from microscopic to over a foot long.
