Looking for some advice for a better salt mix. Currently Im using instant ocean but thinking about switching I was thinking Red Sea. What does everybody else use? Also is there any reason to be concerned when mixing different brands of salt mix when and if I change? Have been using instant ocean for 2 years now since I've started in the sw world and its been good I guess. I mean it's salt mix and is easy to get. But what's everyone else use. Again thinking Red Sea
