HELP: Raising bbs to adults

[HalJ]

Bbs won't live past day three. I have a 10 gal tank filled to about 6 gal.  I use conditioned tap water with marine grade salt (1.022-1.026). Temp is 79.  The tank has a small sponge filter and second air line, both gently bubbling.  I use a Ziss hatchery and transfer a small amount of bbs to the grow out tank.  I feed the bbs 2 days after hatching.  I have tried several methods of feeding spirulina powder.  I've dusted the surface and premixed it with conditioned water and dripped it in.  I have tried half a dozen times, raising and lowering the salinity, and increasing and decreasing the amount food. All with the same results. Any ideas?

It may be your water. Treating tap may not work. You may need to use RODI or distilled water for your salt water. They are much pickier when it comes to reproduction and cyst formation. You could also try a yeast solution in combo with the spirulina and see if that spurs them on.

I have never tried, but there are several Youtube videos about growing brine shrimp to adults. Just search for "adult brine shrimp."

Makes me want to give it a try.
