If you have excessive CO2 from smoke,breathing furnace....... in your house the only way to find out is to take a sample outside into fresh air.If you get a different reading then you have found the problem ,if not you can rule it out.Excessive CO2 will drive down PH.
Let say my Ph is different from outside to in.....do i have to shut the AC off and open the windows????? (it kinda hot in va beach) I don't smoke in the house. Oh buy the way i took some water to my LFS today about a 15 min dive the container was open and the LFS got the same readings.
