do brine shrimp (sea monkeys) eggs expire?

6th grade science teacher here, and part of our new unit involves hatching brine shrimp…aka, sea monkeys. the science kit i have is from 2002, and the eggs in the vial are that old. anyone know if they will hatch? i have some in salt water now, but i’m waiting for the possibility for them to hatch…haven’t seen anythign yet.

thanks

How often should I clean my filters system in my saltwater tank?

I’ve had my tank setup for around five months now and the filter system only been cleaned once. how often should it be clean? I have a Fluval 304 unit.I have a 40 gallon tank. I have… 1 shrimpgoby, 2 pajama cardinal, 2 percula clownfish, 1 cleaner shrimp, 1 red general starfish. All of my fishes diet are different, some eat pellet, flake, brine or meaty. I have my tank water change every six weeks by a prof. however I only had my filter system cleaned once. So again how often should I have my filter system cleaned so my fishes can stay healthy.
Also should i clean my tank more often?
I just had my filter system cleaned two days ago.
