Hi all
The quest for the so-called best salt mix is a long and ardious task
simply because there are too many variables beyond man's control.
reefs.org were very close to conducting a comprehensive test of the
trace elements of various salt. it was put off due to objectivity reasons.
all aquarium salt should be fine long as its not table.
I find the S-15 report a joke. Marine environ & gang are just as good as
what we have in the mkt now.
