A lot of people end up dropping the dwarf hobby because it becomes a big PITA continually hatching and enriching the bbs.
Before the hatching, you need to either sterilize the cysts, or, decap them. This helps to eliminate the scourge of dwarf tanks, hydroids.
After hatching you grow the bbs out for a day until they develop their digestive system and begin to feed, and then enrich them for two 12 hour stages with new water and enrichment for each 12 hour stage.
Because dwarfs don't normally hunt their food down like their larger cousins do, the density of bbs in the tank has to be high so that they can stay hitched and snick the bbs as they pass by.
Leftover bbs have to be removed before the next feeding as they loose their enrichment quickly.
Low water flow isn't a problem as I just use open ended air line tubes in the dwarf tanks.
Some people also like to add mysid shrimp to dwarf tanks for the dwarfs to feed on the mysid nauuplii.
