Regular salt for bbs?

No sure what you mean by "regular salt mix", I have heard of solar salt working but I just reuses tank water from water changes.
 
Definitely don't use iodized table salt.
However, you can use your salt water aquarium salt, or any sodium chloride salt.
I use sodium chloride water softener salt and mix it 10 parts sodium chloride to one part epsom salts and add a little baked baking soda for alkalinity.
While I hatch and grow my artemia at 1.017, they will hatch and grow at a very wide range of salt content. Most people use a specific gravity between 1.015 and 1.030.
After hatching I transfer them to a growout container from which I remove the amount needed for a days feedings and enrich them with Dan's Feed w BG. (after a days grow out while they develop their digestive system)
The remaining nauplii are left in the grow out and fed spirulina powder that has been blended for at least two minutes in water.

"Plain" table salt is fine..."plain" as in non-iodized. It will say "Plain" on the label.
 
That will work best.

Actually commercial salt tanks salt mixes work no better than the cheap water softener sodium chloride salts with epsom.
The cheap stuff is significantly cheaper, and cheaper too than plain uniodized table salt.
I buy a 20 Kilo bag for $6 at Walmart.
 
Its about 5-10 cents worth of salt to make a brine culture with Instant Ocean :) No worries about PH or other missing stuff not found in the cheaper water softener salt.
 
Sorry for that as I often forget that a lot of people don't use a lot of brine and therefore don't use much salt water for them.
Most of the people I am directly connected with in the seahorse hobby are raising brine shrimp to larger sizes up to adult, and that's where the savings come in. Salt prices here in Canada are significantly higher than in the US I believe, most likely due to shipping costs.
For me, I have a minimum of four 26g containers of various growth stages of artemia, and a minimum of 5g of rotifers, and, at any given point, between 20 and 150g of nannochloropsis under culture, so it's a big savings for me.
As for anything lacking in the culture water, I've been doing this large scale for well over a decade and there has been no problem whatsoever with raising them.
When you think of it, the reef salt mix makes salt water that is nowhere near the makeup of the salt water in the Great Salt Lake, and other bodies of water where artemia are found.
It is not even needed for the nannochloropsis as the f/2 fertilizer supplies all that it needs.
