Hi Sgt_USMC,
to TR. Thanks for defending our county!
Even if you buy pre-mixed
SW you are going to need salt to adjust the SpG to match your tank's. I have found that the
LFS around here mix it to 1.019. I keep my tank at 1.024-1.025 so I always have to add salt. Make sure that you always test the
SW, pre mixed or otherwise, before adding it to your tank. I know one hobbyist who killed some fish because the store gave him fresh
RO/DI water instead of
SW.
