Mixing KNO3

I just received my potassium nitrate from aquariumfertilizer.com. Does it matter if you use regular tap water, should it be dechlorinated or use RO water to mix? Or is the dosage small enough where the chlorine in the water won't matter?

At most you will dose something like 50 ml of that mix at one time. That isn't going to do any harm even if it isn't dechlorinated. I just use tap water for my pre-mixed fertilizers. And, I also use tap water for my daily 15% water changes. No problems yet, after several months of doing this. But, my tap water almost never has any chlorine smell, so it is apparently not heavily chlorinated.
