My SPS dominant system uses a lot of core 7 which causes my salinity to rise. Every week or so I exchange some tank water with RODI to keep it in check. This just got me thinking though, does the "salinity" provided by core 7 accurately replace the salinity provided by the original salt mix or is my water chemistry in terms of salinity makeup slowly changing with core 7 absent water changes (which I haven't done many of in nearly 2 years now)?
Thank you
