growing brine shrimp?

[ScubaSteve]

I just use 2L pop bottles upside down with the bottom cut off and an airstone. I keep another bottle of the same design next two it with an algae growing, normally nanochloropsis, but you can also feed with purred-pea baby food. I'd also add a few drops of Selcon. Basically I'd feed them whatever my fish liked the best.
