Things You'll Need
- Ammonia test kit
- Nitrite test kit
- Nitrate test kit
Instructions
Follow the manufacturer's instructions on the test kits and check your aquarium water for ammonia, nitrite and nitrate. The nitrogen cycle produces ammonia first, which dissipates and turns into nitrite. Nitrite levels peak before dropping off and forming nitrate. A new tank setup is very likely to experience all three toxins in the first three months, and if left unchecked, fish will die. Water test kits provide an easy to follow color chart to enable you to see if you should take immediate action.
Reduce nitrite quickly by performing a 50 percent water change if the levels are reading high on your test kit chart.
Add plants to your aquarium. Live plants feed on nitrite and nitrate, helping to stabilize your tank by playing an important part in the nitrogen cycle.
Replace a third of the water every week for the next two months. You should see the levels drop until the ammonia disappears completely. Nitrite levels often spike again at this point, but further partial water changes will make the water stable.
Add a beneficial bacteria solution to enhance the biological properties of an aquarium filter. The microbes speed up the nitrogen cycle and create an environment that reduces toxins naturally. Use the solution when adding fish to your aquarium or carrying out a water change.
