have a new biocube 32 filled with saltwater from my local LFS. I have been checking salinity daily with a Hanna salinity tester. Since day 1 it has been 1.027 after first few days i questioned my LFS owner who is very knowledgeable i thought it might be too high. He said no that was fine as long as it remains constant. Should i add some distilled water to lower it since i don’t have RODI. Or should i not worry about it.
