Test results today are as follows:
Ammonia- .12 ppm
Nitrite- almost zero
Nitrate- 1 ppm
pH- 7.4
(Note: The water has changed over the past few days from emerald green to more pea-soup like.) I'm guessing that as more nitrate became available, a plankton bloom was triggered and then lowered the nitrate levels?
Cecil, after you brought up the affect pH had on ionizing ammonia, I read into the subject. Since my pH is typically higher than what it was during the fish kill, I'm fairly convinced that ammonia toxicity did not kill these fish.
