The problem is usually because they get sucked into your filtration system and croak. Your best chance of raising them would be if you had no fish or other predators in the tank, and you only drew water into your filter from the surface. The less motion in the water, the more likely they will be to stay secure on the bottom.
The problem with all of this info is that none of it is good for a normal tank with coral, fish or other inverts.
I guess you could buy a very small heater air pump and transfer the eggs into a bucket. They might have a chance of at least hatching and growing a bit.
Good luck man
