BRS Two Part Calcium and Alkalinity Solution

[lastlight]

I doubt the stuff available locally is the same grade. BRS a while back also upgraded grades. My jugs of Ca, Alk, and Mg appear to be jugs of clean water. From talking to other reefers a lot of the other bulk stuff is not like this. Not saying that equates to quality but with my small tank I had no problem paying a little bit extra for BRS. It's apparent that my one batch is going to last longer than a year.
