how can i bring the nitrite levels down in my fish tank, everything else including nitrates are safe levels?

Answer 1

The nitrites will drop on their own and the nitrifying bacterial populations develop and grow. It may take another couples weeks until the nitrites are at zero (at that time, you will likely see an increase in nitrates).
In the meantime, do small (10%) daily water changes to lessen on the impact of the nitrites on your fish.
There's not much else you can do but give it a couple weeks :)

Answer 2

Sufficient information has not been provided but here are a few suggestions. If the tank is a new setup, it takes two weeks to go through the ammonia/nitrite cycle- especially in areas where the water has a pH above 7.4. Feed the fish only once a day, what can be consumed in 3-5 minutes and make sure there is no food on the bottom of the tank. When cleaning the gravel bed, do not stir the gravel and clean only 1/2 the gravel per cleaning. One of the best cheapest ways to lower the nitrite is to make a 1/4 tank water change, especially if a water change hasn't been made in at least 6 weeks. Aquarium salt is very beneficial to the tank and especially when fish are under stress from high nitrite levels. One of the best ways to mess up the tank is to clean it too much or too thoroughly.

Answer 3

Nitrites, the second stage of the nitrogen cycle, while being less toxic than Ammonia, are still a detriment to your fish's health, can cause brown blood disease and should be tested for on a weekly basis. As with Ammonia, high Nitrite readings indicate a problem with your bio-filter, or fish load, or water quality. High Nitrate levels can be lowered by water changes

Answer 4

Reduce feeding, perform a 50% water change, using a dechlorinator. Change 20% of water each day until the Nitrite levels are acceptable. Add a bacterial supplement.

Answer 5

I assume this is a fairly new setup. Continue to do water changes daily to control the nitrite levels until the nitrobacter bacteria can catch up and eliminate it effectively. This part of the cycle lags behind the removal of ammonia but will eventually be part of the regular cycle of the tank and of no further concern.

Answer 6

You can get nitrite absorbers that go in behind the filter.

Answer 7

have you got one of them protien skimmers.
