Salinity is a very controversial salt. It works great for some (like in my case) while it worked like the worst possible salt (like in Brad's case). I myself is going to move to H2Ocean (seems like the most stable salt with a nice price being a high end salt) since its parameters are much more stable from buckets to buckets unlike Salinity which has a tremendous deviation between buckets (infact, I exchanged my 2nd bucket for a new one at LFS since the mg was way too low - funny!). IO is possibly the most appreciated salt in this hobby since one way or the other, you will have to dose the tank eventually. I just don't like to dose freshly mixed salt so don't use it. And since I usually get flamed for using "less expensive" products (with "you get what you pay for" motto), I try to give the best salt to my tank - the ONLY important thing for this hobby
