Answer
Hi LAI,

When testing salinity with a hydrometer, directly after a water change, typically there will be fluctuations, due to the temperature change of the water.

Give the water a chance to stabilize to it's normally running temperature, then re-check your salinity with your hydrometer. This will yield a more accurate reading.

Dave
