Ashe Posted October 30, 2020 Share Posted October 30, 2020 Is it normal to have 40ppm KH and 120ppm GH with pH around 6.8-7.2?? I have a concentrated liquid calcium bottle that I am planning to try if it is an effective way to increase the KH. I think my pH reading is wrong and so any suggestion on the the use of liquid calcium or on how to increase KH? Link to comment Share on other sites More sharing options...
Administrators Cory Posted October 30, 2020 Administrators Share Posted October 30, 2020 Typically calcium would increase GH, not the kH Link to comment Share on other sites More sharing options...
