Why is my gh so much lower than my kh?
I use mostly RO with enough tap water to bring it up to temp. I use an API hardness test kit and my kh runs around 6 but my gh is at most 1.
My well water is quite hard so I soften it with KCl.
Other parameters for my planted 20 gallon tank are:
PH is 6.8
65 watt Coralife fixture
I almost always see gh higher than kh. Why is that not the case with my aquarium?
Next, I'm about to start EI. Does this really matter and if so how should I compensate?
