I was having issues with my params and started dosing mag and ca. I only dosed alk twice and it was stable so didn't continue. My mag seems to be an issue. After water changes it often drops in my 15g although this week it looks like it went up. Ex. My mag was 1040 when i started dosing and has fluctuated between 1140-1240 after dosing. I find after a wc it drops to 1140, this time my test showed 1410 after water change. My ca has been fine so i am not dosing that now. My alk however is 5.5 meq/L Is this high? What can I do if my alk continues to rise? I have been trying to figure out how much my tank uses but with my mag results being different more frequently than not-i can't figure it out.
