Hey guys. I'll post a new pic soon, but in a nutshell, things have not been great in the tank this past month. Which is totally, 100% my fault because I made a really n00b mistake.
I bought a Jebao dosing pump a few months back and dialed it in. But I was convinced I had not calibrated right because the levels of alk and calcium remained consistently low/would drop if I stopped supplementing manually. So I kept nudging up the mL dosed per dosing on the machine, thinking that EVENTUALLY I would make up for calibration issues and it would dose enough to keep things stable.
Turns out, I had the interval set wrong. It was only dosing every 30 days. So the levels would be low for 29 days and then would shoot up on day 30 because I had increased the doser so much to compensate! Ugh. Such a n00b. I seriously can't believe I did that.
Anyway. I am sticking with manual dosing until things are back on track. I'm very lucky in that only 2/3 corals seem to have suffered, and the third one (the only expensive piece, my atom bomb chalice) is fine-- not as colored up as it was before but still growing and not receding. So, I got very lucky.
I will post again when I get this fixed.
Live and learn right?
