The key to the whole thing, the lights must remain on 24/7!!!
Don't just think that you can just throw them in a bucket of slt water and come back in a month.
BTW, the little hatchlings can take a while to catch because they are so small. I used a syringe and just sucked them up, added directly to salt water.
To measure salinity, use a hydrometer to measure specific gravity (their is no direct way to measure "actual" salinity", only the specific gravity of the solution at a specified temperature.
You can tell when the zoes are about to hatch by a the appearance of a very dark shadow under the shrimps belly. It gets darker right towards the end.
Good luck.

You can also use a refractometer that measures the refraction of light by differing concentrations of salt water. They're a bit pricier though, so if an exact salinity level isn't crucial, go for the hydrometer.
Good luck, post pictures, and detail your progress! I've had berried amanos before but thought it'd be too much work. Maybe I was wrong.
