cheats way of hatching brine shrimp in brackish water

[spoon]

i have a small brackish tank with 2 mollies and two bumblebee gobies(btw looking for more!) i wanted to hatch brine shrimp so i thort about this and im now using an old gupping fry trap one of the cheap plastic 1s i put this in the tank and sprinkle the eggs on top they are held in the surface tension as there is no turbulance in it, they hatch overnight (these are the nz brine shrimps) 2 feed them out simply lift the trap 1 or two centimetres out off the water this sucks the 1s in mid water out into the tank thru the gaps in the bottom of the trap while the un hatched eggs and shells remain at the top , and they will still live and possibly grow inside this once u think all the eggs are hatched use an eye dropper to suck them off the top then do a last final feed of the mid water 1s,. perhaps this could be improved with a lite proof lis and sides so they naturally swim out to the bottom , however i dont think i will do this as my filter will get most of them i turn the filter off 4 a few mins while feeding so so they arnet sucked away.
