Newer to the hobby and am quickly learning how unreliable the Apex salinity probe is. Even after careful calibration, it was still underreporting around 3-4ppt. I have been slowly trying to lower the salinity over the past few days, but with evaporation on a 150gal tank, it's taking a lot longer. Right now, I am just removing 2-3 gallons of tank water and replacing with RODI water. I am at about 1.0275 and am trying to get it to 1.025. I like 1.025 because where I get the majority of my coral from at the LFS, they keep theirs at 1.025.
How big would a .002sg swing be on a 150gal tank?
