Two dead amanos found this evening. Not sure what happened...
I've been dosing ferts via EI method. Been doing this for three weeks and haven't had an issue.
I do CO2 injection - it's pretty high and my drop checker is light green / yellow. But I've kept it steady for several weeks now, so I didn't worry too much about it.
HOWEVER: yesterday, I did remove my HOB filter. I still have an Eheim 2217 + Eheim 2213 still on the 30 gallon tank, so it's definitely enough filtration. My water parameters are fine - 0 nitirites/ammonia (nitrates varying with how long I'm into my week of EI dosing - but nothing out of norm). My best guess is that the HOB filter was providing all the water agitation (which diffused some of the CO2) and without the water agitation now, my shrimp died of CO2 overdose.
Does that sound possible?
