I have a 125 that has been up for a month now. I have been running tests on it with some Hanna checkers. My alkalinity 3 days ago was 97, I added some brs soda ash and it dropped to 85 yesturday. Just wondering why it plumited like that, when a week ago it was in the 200 area. please help!!

Did your tank fully cycle? What are your Alkalinity measurements in DKH? What does your Calcium test at? also what is your magnesium? Do you have any alk depleting livestock in the tank?
