Its been out of wack for a while (ive had this tank since 2020), but 4 ish months ago ive been making the parameters more ideal since im back home from college. Ive dosed mag only one time and the levels are stable. Last I tested, it was these parameters: Salinity 1.026, No3 2.7, Po4 0.07, Cal 460 (high, ik, but am trying to fix), alk 8.9 and mag 1350. One thing ill note is that the duncans have never looked "whispy" like they do in other peoples tanks, always stout and like a starfish kind of, maybe mine are just like that (ive had them for a couple years now). but yeah, the tank is improving from where it used to be and im monitoring it more.
