Now Im not fully understanding the diagram they provide with the test kit
The diagram is as follows.....
# of Drops | °dKH | ppm KH/GH
1 1 17.9
2 2 35.8
3 3 53.7
4 4 89.5
5 5 107.4
6 6 125.3
7 7 143.2
So can someone help me out here, what exactly does this all mean? Is my water not as good as we maybe thought it was? Thanks for the help folks.
Did I read that your test kit is an Aquarium Pharmaceuticals? If so it's the same one that I have.
Your KH @ 3 degrees hardness is at the high side of the low scale. Meaning 0-3 degrees is the low range of Kh. If it gets too low you could see rapid Ph swings. But it's not horrible.
Gh of 7 degrees isn't terrible. It's a bit harder but HARD water is 11 degrees (200 ppm) and up. Do you have something in your aquarium that is possibly raising your Gh? To be at the lower range of Kh yet have a higher Gh is kind of backwards. Softer (more acidic) water has lower Kh and Gh readings. Are there sea shells, crushed coral, anything that may be adding calcium to the water? Limestone, marbel, etc...
