The best and safest method is through daily partial water changes, about 30-40% of total tank volume. Use only aged or conditioned water that is temperature matched to prevent stress or shock. Recommended water conditioners are AmQuel, NovAqua and StressCoat. These can be purchased online or in most pet stores or fish stores. A home test kit should be used to monitor levels. If a tank is properly cycled, beneficial bacteria will break down these toxins. Overfeeding, excessive light or heat and dead plants can cause spikes in ammonia and nitrite levels.
