I raised Africans for years but got out of it now back into it,oh well.Brine shrimp just need heat and turbulence,What I found worked best for me was to use a
2.5 gal.tank and heat the water with any old hang on tank one,Heat the water to your desired temp,Place a old bottle so the it is filled above the water line,this will keep the water temp constant around the entire bottle,add salt and brine shrimp eggs.agitate with a simple air stone then wait.
This was the best unit that I made work and had many compliments on its effectiveness.
Good luck and I hope it works as good for you
