Sulfur value.

Hi Randy,
After reading several triton test on one commercial salt showing values of sulfur roughly half of those in NSW, I wonder what consequences for a a reef tank, expecially for corals, can be keeping these values.

Unfortunately, I've never seen any study of the importance of keeping sulfate at natural levels, rather than too high or too low.

There may not be any big effect, but I'd suggest trying to maintain something close to natural levels.
