Hey there , recently started a small tank and used instant ocean salt mix to start up with because it was convienent and easy for me to get at local store at that moment. Now I plan to do a water change to bring down nitrates , but is it safe to now use Red Sea coral pro salt mix ? Just a thought and don't want to mess anything up.

. a 200g box of io should cost about the same as a 175g bucket of rscp.
