I use Bio-Sea MarineMix, but I don't buy it from these folks. I'm very
happy with it, but one can find people that are happy and unhappy with
any brand of salt. Bio-Sea costs about the same as IO. (IMO, the cost
of salt is so small compared with the cost of just about everything else
with a reef tank that the cost difference between brands is insignificant.)

How do you calculate this? Depending of how much and how often
salt is very important item on the budget. Other stuff like skimmer
or pumps you pay for once and use them almost forever - salt you
use on regular basis for water changes.

Anybody knows where the full S-15 report is located?
