Do flourite increse water hardness?
So I checked the water that comes out from my tap and it is 3 degrees gh. But when I pour the water into my tank with all flourite substrate and tested the water again, it came out to be 25 degrees gh. So I was suspecting the test kit was faulty so i bought a test kit from another brand and the results are the same. So does anyone here knows whether or not the floruite cause the rise in gh or is it something else?
