Seems odd they haven’t made one for saltwater, I imagine there would be a market for it. I’ve been debating on jumping to Hanna checkers but prefer to use one brand for all my tests. If they ever figure it out I might make the jump but for now I think I’m gonna go from api to Red Sea since my lfs carries them.
