Lost Tetra KH and GH directions
I looked at my test kit today and noticed that I’ve lost the directions for my KH and GH (Tetra/Laborett) test kits. I know that they are titration style kits but I can’t remember if the drops stand for one degree of hardness each or what. (I used 5 ml of water for each test) Does anyone else use these kits?
Thanks
