HELP HELP HELP SERIOUS PROBLEM!!!!!

[Nano]

seeing as though I know my hydrometer is off by .003 cause it was just compared to a refractometer on wednesday, I made a mistake saying it was 1.023, I checked it 5 times and it reads 1.0215(so + .003=1.0245) so my actual salinity is 1.0245 so its just slightly low, but tomorrow I am going to have my hydrometer checked again as well as take a water sample for testing, and replace the bad alk test kit.
other then that my params
PARAMS
Salinity 1.0235---actually is 1.0245
CA 320-----accurate but bringing it up slowly
ph 8.1 accurate
Ammonia 0 ppm accurate
Alk/Kh 27???? WTF?--broken test kit
Phosphate less then .25---is this ok?
Nitrites 0 ppm---accurate
Nitrates 0 ppm---accurate

so all this being said, should I still hold off on my fish purchase if this is my actual parameters? or are they in fact ok?
