| he he they hide well, thats why you dont see them. Also keep in mind many of the "pods" as we call them are itty bitty as in less than 800 micron, shine a flashlight into the rock crevaces at night and look for little things swimming around, it's quite fun when you get a good population.
For now though, it appears the algae shaking method is working so might as well stick with it! Once you find something that works your in good shape I've found (no matter how many of us idiots tell you your wrong he he)
