[APD] water hardness questions
I finally invested in a water test kit after many years of owning tanks. My
water in the tanks is tremendously hard GH: 11-17 and KH: 9. My tap water
if only GH: 4 and KH: 1. What could be increasing it so much? Is that
really bad and how do I lower it. I know there are softener pillows, but
they say that removes Calcium and Magnesium and I thought my plants need
that. What else softens water? I add Amquel, neutral pH buffer and
aquarium salt to my tanks. Filter medium only has charcoal. I am slowly
trying to get more into plants and am going to try adding CO2 (via the yeast
method) to some of my tanks. I know the KH and CO2 affect the pH, but the
adition of CO2 won't actually change the kH will it?
