Also test kit might be expired. I'll take it to a LFS soon for a second opinion.

Also I've been using plain tap water since day one.

hydrometers are never spot on they need to be recalibrated very frequently, they are notorious for being off. if your salinity on your hd is 1.027 it could even be higher. take a sample or the hydrometer in for recalibration if you dont do it reguarily
