Huh? Corals bleach out from high temps or to much light, not the brand of salt you use. There’s people on here that change salts all the time. And BRS even did a video on the benefits to changing salts if you want to run parameters closer to where you want them. There are no issues with changing salts, you just need to do it graduallyOh how big is you tank . I had a problem with rpm my coral was bleaching out with in my 6 water change so I stop and use the same salt witch is I/o I figure out that once you start a tank with a salt mix stick with it cause when you want to change salts bad things happen for a reason lol
