I lowered my light intensity a month or so ago and when I did I noticed my sps stop growing (encrusting) I have about 20 frags. My alkalinity was locked in at 8.4 for several months. When I checked it was 8.7 and I started getting some burnt tips. I stopped dosing kalkwasser about five days ago and I haven't done any water changes or add anything else. Why is my alk not dropping? 5 days ago my alk was 8.7 my calcium was 500 and magnesium was 1350. Now alk is the same calcium dropped to 460 and magnesium dropped to 1260. My corals seem to be growing again also which is why I'm confused why everything is dropping but my alk. I use a hanna checker. I tested a new batch of water and it tested where it should have so I dont feel it's the hanna checker. Anyone have any idea why it's not dropping?
