First, I would do a partial water change which in itself will remove a portion of the ammonia. If you remove 30% of the water, you will remove approximately 30% of the ammonia. Second, in regards to Diamond Blend, there is no tried and true formula for how much carbon should be used per gallon of water, etc. I would recommend placing approximately 1/4 cup in the filter bag, and then rinsing it LIGHTLY for just several seconds. Place it in front of the filter, closest to the tank. You can use as much of it as you like, just as long as it does not cause the filter to overflow around the intake tube. For best results, change it weekly.
One other note - if your ammonia is high, your tank is either new or imbalanced. After the water change, let the tank settle down, and then add SafeStart Plus, a cultured bacterial product under our other brand, Tetra. This will help finish removing the ammonia and re-establish your biological filter.
