dude you dont have to bump 10 minutes into your original post.
first of all buying a brine shrimp hatchery is a waste of money no matter how much you paid for it, you could have made one out of any plastic bottle with a lid.
growing out brine shrimp is hard as hell and from my experiments for the past few months is a waste of time. from a newly hatched batch in a 500ml jar the survival rate for me is about 5% if even that.
also from what i read if you feed brine shrimp to fish after the initial period they are hatched they lose all nutrition and is pretty much 98% water.
