I've been using Red Sea Coral Pro for the last year or so and after speaking with a couple of very successful reefers who have had great results with Seachem, I've decided it's time for a change. What's the safest way to change brands? Should it be gradually mixing the twobfor a period of time or just do a water change like I normally would with the new salt? I ask because I read a blog where I reefer claimed that his tank crashed due to an abrupt change in salt. Any ideas? Thanks
