I have a 105 with numerous corals and do a 20 gallon water change weekly with reef crystals as my salt. I test my water and my Calcium is 900 and my Kh is 8.4--very steady. I don't understand why my Kh doesn't drop throughout the week, with the corals likely using it up?
I know the important thing is to keep the levels stable, but it doesn't seem like I even need to dose?
Thanks
