Help! My triops is not hatching after 40 hours!?

Okay i am going to be as detailed as possible.
31st December 2011 5.30pm-I bought some triops eggs. I spread the eggs with sediments and some leafs that came with the pack into the plastic container “tank”
I checked on them every 30min-1hr
1st January 2012 10.30am- I went to check on the eggs. Still nothing. I cant even see the eggs.
1st January 2012 5.30pm- I still see no triops hatching but i can see the triops eggs floating on the water surface. I tried pushing them down gently but to no avail (my pack told me to do that)
2nd January 9am- 40 hours after i threw them in the water. Still nothing.
I am using bottled spring water i bought from a store. The water temperature is around 24 Celsius to 28 Celsius. If you need any more information i will try my best to answer.
I am rearing T.longicaudatus
I am using spring water not mineral water. This was what i was told by the people from the store.

how long does it take for sea monkeys to grow?

i had sea monkeys and its been 2 weeks since i put them in and all i see is little things swimming around about the size of a millimeter or a half of a millimeter so how long will it take to get full grown. is it a glitch and they wont grow. I heard that they can live 2 years so maybe it takes longer to grow then triops because they only live for 2 weeks or 3 weeks but they grow fast but maybe since the sea monkeys live for 2 years they take a wile to grow. so how long does it take

Could I use goldfish aquarium water for triops?

I want triops and have a 55 gallon goldfish tank. Could I use the tank water instead of the distilled water? Also could I use goldfish food to feed them?

Is this ok for my future Triops?

I have a 2.5 gallon tank ready , with a cave and water conditioned and aquarium salted water
Is this ok
Since this is a larger tank for them how long will they live?
Do they breed quick??
Breeding signs?
Anything else or tips
Can I feed them tropical flake when I run out of triop food
