Within the past two months at work, we've had two major dieoffs: no clue as to what killed every fish in our reef tank but left all the delicate inverts and corals untouched, and then nearly a week later, another disaster: a 29 gallon Congo tetra tank, and a 55 gallon Lake Malawi setup. Both of them are planted, or were at the time, and this is when the problem starts.
I've used SeaChem's Flourish and Comprehensive supplements for a year now, and never had a problem with either product. However, on that date, I finally read what the bottle said to dose the carbon. My boss had always told me one capful per 50 gallons, but according to the bottle, after a major (over 40%) water change, to dose one capful per 10 gallons. Well, I do 50% changes regularly, so in went more carbon! First the Congos, and then Malawi, and at last the planted bichir tank got the extra doses.
Within ten minutes, all the Congos were gasping for air, as were the cichlids. We lost every fish save for one in Malawi, and lost six Congos.
Malawi is now restocked, unplanted, and I no longer read Flourish's orders on the dosing! I'm just glad I didn't overdose the ferts on the discus tank!
