Are you sure about that though? My refractometer has been measuring salinity fine. Plus I don’t really think salinity can be an issue because my salinity has been At that level for more than a year now. Plus only some corals are being affected. I did a 25% percent water change last night I’ll test again to see if my parameters have changed.Do you mean this?
If so, i suggest you get a proper refractometer. Swing arm hydrometers can be off by a lot.
