1 Liter water, one air stone (moderate to low flow), 10ml eggs (or whatever amount you want to decap)...
Set air going and dump eggs in water. Let soak 1 hour with aeration.
About 90ml (amount not critical) of unscented household bleach or (what I use) swimming pool chlorine.
Watch reaction instead of a clock. Eggs will turn gray, then brownish, then orange. When they turn orange, they are done. Strain through handkerchief. Rinse VERY well with numerous water changes. Last rinse add about 90ml of vinegar, then rinse again.
Use within a few days (as long as 1 week is OK) as is or make up a brine solution by dissolving non-iodized salt in water until no more will dissolve then cover eggs with brine. They will keep for months like that.
You can feed these directly without hatching them or put them in a regular hatcher and they will hatch just fine (usually with a better hatch rate to boot).
But I never bother to hatch them. They are used only long enough to get my fry to the stage where they will take microworms, which is only a couple of days. I then keep a pretty high density of microworms in the fry tank at all times. Actually, fry take microworms almost immediately anyway, but the brine shrimp eggs are easier to see if being eaten. The fry bellies turn orange.
