Welcome to the forum! What salt mix are you using? Do you test it before using? Some salt mixes have high ALK and if it’s not being using by corals your water changes could actually be driving it up.

14.99dKh to 14.95 dKh really isnt much of an increase. Personally I wouldn’t worry about that at all, thats down to chasing numbers.
I would be more concerned about the 14dKh number as a whole, its very high. How are the corals doing?
If you are not dosing anything I dont understand how the dKh gets that high. I dont know of any salts that high. Red Sea Pro is only around 12 dKh so how it went even higher without dosing is weird. Have you cross checked the dKh with another source? Salifert for example.
I dont know theTrident but has it been properly calibrated? That would be my first thoughts.

Wouldn’t water changes remove the same amount of kH as the water your putting back in? Assuming no dosage or usageWelcome to the forum! What salt mix are you using? Do you test it before using?

Yes it would but if your not checking SG like you said and it’s higher than normal now your DKH will be higher as well.

if he happened to get a bad batch of salt mix with higher ALK than his tank and assuming there is no uptake his Alk would rise, thats why I asked if he tested his fresh mixed saltwater.. lots of other potential causes such as improperly mixing resulting in high salinity which would raises values as was pointed out by others.
