Planted Nano Water Questions

I have a 7.5 gal planted nano, it's just 2 weeks old. It's my first planted tank. I have used the walstad method to set it up (potting soil + sand as substrate and i have a lot of plants in it).

Water Stats:

PH 7.2
GH 7
KH 20 !!!!
NO2 0.5
NO3 25

My tap water stats are:
GH 7deg
KH 6deg
PH 7.6

I need to do a water change - but why the heck is the KH so high? I'm using some test strips / dip sticks to do the tests. What should i do to lower it?

Right now i have 5 neons and 2 xiphos in the tank.

A lot of areas in the United States have hard water (large amounts of carbonate). Also if you have rocks in the tank they may make it worse.

What type of sand do you have? Some sands, like aragonite, will raise the water hardness.
