Feeding dwarfs question

[Meus]

For about a year I have been designing an automatic brine shrimp hatchery. I have ran into many bumps and such and I though I had it. But, after reading it appears that brine shrimp need to be enriched. So, my question is, how long should the nauplii stay in the hatcher to be enriched. I have provided a paragraph below on how it works:

My hatchery consists of a mini refrigerator, a hatching area, and two reservoirs. The process starts with decaped brine eggs in a super saturated salt solution are dosed into the hatchery. From there fresh water is pumped in to make a perfect mix of salt mix and water for hatching. 18 hours later an enriching agent is pumped into the hatching unit. Now, I need to know how long this solution needs to sit in order for enrichment. Ideal would be around 24-29.75 hours. From there the hatching water is drained. Fresh water again is pumped into the unit and drained. Finally, saltwater from the display is pumped into the unit and the brine shrimp are flushed into the aquarium.

I know you may have questions on how these processes take place, but I assure you my design in perfect. The only thing that I have not figured out is the enriching time and enriching material. So, if anyone wants to help feel free. Also feel free to ask how everything works, if you must. However, I would prefer to keep the design of my hatching unit a secret for now.
Thank you for your time, Meus.

I have a few comments on your intentions, first being that you appear to be placing the enrichment into the hatching water which is a no no.
Second, your hatching may only begin to start at the 18 hour point and continue for many hours afterwards as they don't all hatch at the same time.
Next problem is the fact when hatched, the nauplii have no developed digestive system so you need to grow them out for a day until they have all developed into the Instar II stage, (in new clean salt water) and then enrich them.
Before enrichment begins you rinse again and place in new enrichment water for 12 hours followed by a rinse and new enrichment water for a further 12 hours.
Next thought is how you separate the garbage from the live nauplii because if you dump everything in you are going to put a severe strain on your biological system and likely fuel nuisance algae and bacteria.
IMO you seem be making a relatively simple process into a difficult situation.
A few inverted pop bottles work extremely well.

Thank you, I have things to think about. Also, The waste water does not go into the aquarium, that is what the second reservoir is for. I know this is a simple process, it is just that I am not always around to hatch and feed shrimp twice daily. But again, thank you for the information.
