10 gallon that won't cycle

I have a ten gallon tank that won't cycle. It has been running about three weeks. I have three White Clouds in it. I used a quick start solution, from my LFS. The water is clear, there is no Ammonia, but the Nitrites are 100PPM. I have added SeaChem “Stability” to the tank. Do I need to restart this tank?

More information would be helpful. Is this a planted or unplanted tank. With a planted tank, heavily planting with floaters and fast growing stems will dramatically reduce the time nitrites remain elevated, at least in my experience. With unplanted tanks and conventional cycling a prolonged nitrite spike is not uncommon and sometimes indicates a stalled cycling process. Many people get around this by adding another filter with established media, increasing aeration via airstone or increase surface agitation, or in some cases some claim that a dropping PH to critical levels causes the stall in the cycling as the bacteria needed to complete the cycle do not have a tolerance for too low PH levels, so some people will do some more water changes 1/3 or so to reduce the risk of nitrite toxicity to fish and to bring PH levels back up and jump start the cycle process again.

Cycling takes longer than 3 weeks - if you have nitrites then it IS cycling. Have patience, grasshopper.
