Help with fish death/diagnosis

That depends on the system the invertebrates came from. Some dealers house those in fishless systems, those are fine. If not, then it is safest to restart the fallow clock from the date the last animal was added. In many cases, I’ve just added 30 days to the time and it seemed to work.

Appreciate your response. There were fish in there and I’d rather be safe than sorry. Like I said , I learned my lesson.
