High Nitrite
« on: August 31, 2011, 07:49:14 PM »

What should I do about really high nitrite levels in a 38 gallon tank with two shubunkins?  Everything (ammonia, chlorine, pH, acidity, etc.) was in safe limits (although nitrate was pushing it a bit).  I'm thinking that the new tank is on the end of its cycling, but how can I bring down the nitrite?  Wait it out?  Ask the fish to "go" more to raise the ammonia?  Buy a plant or get some algae going?  Suggestions?

I'm assuming this is a new tank you are trying to cycle and you have another aquarium that has an established and mature biological filtration system. The best thing would have been to stick a new aquarium filter on the established tank and let the nitrifying bacteria establish in there for a few weeks and then use it in the new tank.  If you can transfer some gravel from the mature tank and put it in the new 38 gallon tank, this will help greatly  because there  is a lot of nitrobacter (the nitrite reducing bacteria strain) on the gravel and the nitrite level should drop.  Another thing you can do is borrow the filtration system on the old tank and switch it over to the new 38 gallon tank  for a while ( only do this if you're not trying to quarantine the two shubunkins since you don't want any cross-contamination of diseases) or you can take some biomedia (foam,etc..) from the mature tank and place them in the new 38 gallon tank to give it some additional nitrifying bacteria.  

Live plants are always helpful in reducing the harmful stuff like ammonia, nitrite , and nitirate. Partial water changes should help in reducing nitrite and nitrate also.

I agree with nabi Smiley

Another option is changing the water, of course, if the nitrite is high, a 50% water change usually works on anything Wink And add lots of beneficial bacteria! Some people add salt,  because that helps the fish endure a nitrite spike, but salt also slows down the working bacteria, so that's not the best thing to do in a cycling tank.

The previous speakers are both right.  Smiley In my experience, when I've had a nitrite spike, it helps to do a large water change (as already stated by Nossie) and maybe add a product such as Prime, which allows cycling to continue uninterrupted while detoxifying the nitrite, making the water safe for your fish.

Keep a close eye on them as well, and watch for signs such as burns (white patches), flashing, and blood on the body and in fins. I wouldn't add salt just yet unless you get warning flags such as these and need to help your fish.

Here's an update:
We put the shubunkins back in the old tank.  All of the fish couldn't be happier.  We haven't had any water quality issues with so many fish in the old tank, and they all seem to be enjoying each other's company, so we decided to keep them together.  It seems best all around.

Good it all sorted out Smiley
How big is the tank and how many fish?
I also wonder how often you're testing the water?
