Salinity was a salt I used in the past and really like and didn’t have any issues, it just got to be a pain finding it locallyEDIT: I forgot SeaChem's Salinity. Worst salt ever. Smelled like pee when mixed and against my better judgement I attempted to use it. Crashed one of my earlier tanks. I used 3/4 of that bucket as driveway snow melt. I believe it was around the same time one of the Atlanta's group bought it and had the same results.
