Controlling Ammonia Levels By Feeding

[Bill Moore]

Learned today that the way to control ammonia levels is to stop feeding the fish.  We were overfeeding and that drove ammonia levels really high in the 8+ ppm range (tubes on the left of photo). Taking what I learned in Knoxville, I stopped feeding the fish for two days and the tubes to the right illustrate how depriving the fish for two days dropped the ammonia level. The two right-most tubes show what happens when you start feeding again.  The front-most tube is before feeding them this morning. The tube behind it is 40 minutes after feeding them. Notice how ammonia rises again.
