I now have my decapsulated BBS. I've read different things about salt. I've seen to add rock salt, I've seen table salt, and I've seen marine salt. Which of these if any should be used? Also could I just use my regular saltwater that i have in my tank. I have a 5 gallon jug for water changes in my tank....can I just use a bit of it to hatch the shrimps in? the sg is 1.023 in the sw I have I believe. Any help???
