I note you said you added freshwater to your tank.I'm assuming you didnt mix it with sea salt.Whats your salinity/specific gravity exactly as for saltwater you want salinity/specific gravity to be 1.020 to 1.023 at 75F.If your salinity/specific gravity is within the correct range I wouldn't worry about it.

Jen SG is specific gravity.You use a hydrometer to get reading for it.

Salt doesn't evaporate so when you are replacing evaporated water you always use fresh water...preferably RO water....When you do water changes and actually remove water then you replace it with salt mixed water....
