Dawn T Posted December 2, 2021 Share Posted December 2, 2021 My GH and KH are considerably higher. Hard water here. KH tends to be 80-just over 120 ppm, depending on the tank. GH stays up around 300 ppm. pH right around 7.4 - varying by no more than about .2 above or below that from tank to tank. Link to comment Share on other sites More sharing options...
