Does Instant Ocean have Nitrates or Phosphates in it?
Coralife, Oceanic, Red Sea, Seachem, Kent, and Tropic Marin each say no nitrates or phosphates. I'm sure, I'm just tired and reading into things. Instant Ocean just states that it's been around for over 40 years and brags on itself.
I saw this on another website that sells all of these brands of salt.
