How do you lower seriously high nitrites in a goldfish aquarium2007-11-24 23:33:44

The nitrate level is okay, pH is acidic and alkaline is low. The ammonia meter says that ammonia is at a safe level. Any suggestions?

Answers:

Water changes of 30% daily or every other day until you get the nitirites to 0. Nitrites are highly toxic to your fish. You can also get some Bio-Spira or Stability, they have nitrifying bacteria to help convert your nitrite to nitrate. These two products are the best, others just don't work very well. Are you sure it's the nitrite that is high? If it's the nitrate, water changes are still in order, but your fish are not in as much danger. To lower nitrates you can add some plants like hornwort or moneywort to absorb them. Good luck.

Frequent partial (30%) water changes and/or a benifical bacterial culture such as eco-start will help break down the nitirites into nitrAtes. You might be over feeding or over stocked. You need 10 gallons of water per fish for goldfish.good luck!

First do a 25% water change now. Then post more info. How big is the tank? How many fish. How did you cycle the tank, and how long has it been set up? Finally, how high are the nitrites? Numbers of all the water parameters would be helpful.

Frequent water changes.

and suck up the gravel too. goldfish poop a lot so taking out the waste is good.

Frequent PARTIAL water changes. Dont clean the tank excessivly because it'll destroy the biofiltration. Also, the only "safe" level of ammonia is 0, just like the only safe level of carbon monoxide in your home is 0.
