Review title: Reading is too high
Product review: I bought this to compare to the previous generation of Oceanic Hydrometers. Even after breaking in, it read 0.004 higher than my old meter. This prompted me to buy a refractometer which confirmed this hydrometer consistently measures 0.002 higher than the actual salinity.This product is fine for fish, but I wouldn't recommend it for a reef / invert. tank.
