You are right on target. The tap water after one hour tested 3ppm CO2.
I added the "Proper pH" by Aquarium Pharmaceuticals (not American
Pharmaceuticals by the way) because my water was slowly dropping in pH. I am
using DI water so I need to add trace elements, but the buffering was not
keeping the pH steady.
Thanks for the advice, I am now proceeding with the water changes.
