Hatching Brine Shrimp

I have had my brine shrimp hatchery going for 3 and a half days now and they still haven't hatched.
I've checked off each thing required to hatch them and still no luck...these include:
- brine shrimp eggs
- an adequate water temperature at 28°c
- constant air flow to keep them in circulation
- 2 tablespoons of rock salt
- and a constant source of light

Now here's a few things that may be the cause of them to not hatch which I'm not entirely sure on that's why I'm posting this thread to see if you guys know.

- too much or not enough salt
- eggs are of poor quality (even though the packet says premium quality)
- the source of light is white L.E.Ds, does the light need to be orange?
- I did try using a pinch of gluten free baking powder - this is the one that's making me believe this is the reason they won't hatch

But if anyone thinks otherwise please let me know and I'm open to answering questions you may have.
Thank you

give artemia for thousand of larvae can be a hell.
search this: microworms, daphnia, Cyclopidae, turbatrix aceti :blob:
this is the easy live food, but someone has some problems with daphnia, cause the culture can stop suddenly.
