I have a dirt substrate Walstad tank. It started out with kH 4 and gradually rose to kH 6 as the plants filled out in two months. I haven't done any water change or dose anything.
What is causing the rise in kH? Does it mean my gH is also rising?
I only have a kH kit and haven't tested for gH for ages. My water company reported kH 4 and gH 6 in my tap water.
