The trout are doing really well. We've only lost one in the last month. Water chemistry is, for the most part, stable. We are experiencing a nitrite spike, though. Students are researching to find out what we should do. So far, the water quality test team has determined that it may be due to over feeding. So, we're feeding them slightly less of the size 2 food.

Usually you will see an increase in the ammonia level followed by an increase in the nitrite level. The bacteria in the tank convert ammonia to nitrite which in turn is converted to nitrate. The latter is relatively harmless to the trout at low levels. Check your ammonia readings for the past 7-10 days to see if they increased. If they did you can expect the nitrites to increase later. Your suggestion of reducing the amount of food fed to the fish may be the solution to reducing the elevated nitrite levels. Good detective work! Mr. Dinkel ><>
