I'm just throwing it all in to the DT typically, and if the fish don't get them corals will.
But..... I also hatched a few extra, and threw them into a small plastic tank with some WC water. I mean if you're going to throw it out anyways, might as well try to experiment with it. So every week, I do a water change on the growing brine shrimp, and after about a month, I have adults who clearly have eggs on them. I harvested a baster full, put them into a small container with water from my display, (sieved and returned the crap water back to the tank) and put a drop of selcon into it. Water turned milky white of course. About an hour later though, the water was clear. So the crap had filtered most of the selcon out of the water. Fed them to the fish, and they chased them down and gobbled them up quick.
Edit: I fed the brine shrimp phyto and spirulina to grow them out. It's kind of expensive feed, but I had it. When I run out, I'm probably just going to try to feed them spirulina and maybe a pinch of brewer's yeast, and enrich them with selcon before I feed. Alternatively.... you could also just feed them selcon.
