Why not try lowering your alk dose.... 
 
I test my alk with Hanna vs salifert and the difference can be about .4-7 on the salifert. 
 
But let's say if your alk is at 8 and your dosing 220 ml per day and it's rising why not first try to adjust your doser 6 points belowso 210ml or 214ml per day and see if it stabilizes out. I think salifert is abit higher readings than the Hanna but this could only be for me...
