Reduce feedings by half Continue reduced feedings Chemically neutralize ammonia
Watch fish for signs of distress Lower pH below 7.0

1 Begin ammonia testing on third day after aqaurium has been set up.
2 Plot test results on chart daily until values drop to zero.
3 If results are in the shaded areas, take appropriate steps as shown.
4 If at any time the fish show signs of distress immediately take steps shown for > 2.0
Water Changes
Use water that has a lower pH and the same temperature as the aquarium water.
When changing water remove any uneaten food and other debris.
How to Lower pH
Filter water using peat.
Use water with a lower pH when doing water change (R.O water, or distilled water).
Use a pH lowering agent such as pH Down.
Chemicaly Neutralizing Ammonia
Use a commercially prepared chemical such as Ammo-Lock, according to manufacturers instructions.
