View Full Version : Nitrite Increase close to end?
11-14-2011, 02:24 PM
Ive been cycling my tank for almost a month now. Towards the end of last week and over the weekend, the nitrite was getting very close to zero. Nitrates were also increasing to 20. All of a sudden today I did another test expecting to be finished if not very close, and I have another nitrite spike. It is now 5+.
Is this normal? What would cause this? I havent done anything to the tank exept add ammonia and test daily. I have been adding enough ammonia to hit anywhere between 1 and 2 ppm each day.
Todays test numbers before ammonia addition
Ammonia - .25
Nitrite - 5+
Nitrate - 20
Please advise. Thanks

Totally normal. You are continuing to add ammonia which is continuing to convert to nitrites. Should have been done cycling by now, tho.

Should I do something different? Or just keep at it?
Would dead plant matter stall my cycle?

Not likely but why is there dead plant matter? Remove what is dead and your plants will grow better anyway. I don't know why it's taken so long, tho. Generally a tank will cycle in 2.5 weeks. Have you messed with the filter by cleaning it or anything? Is your ammonia registering 0 each day?

The dead plant matter is all small so the only way to get it out would be to vacuum. I know that Im not supposed to so I havent.
I havent touched the filter at all....and my ammonia reads between 0-.25 every morning...
When I first got this tank I seeded it from my moms estabilshed tank. Out of my own stupidity I didnt feed the bacteria ammonia so it all died so I started the ammonia about 2.5 weeks ago...so I guess its really only been cycling for 2.5 weeks if you count it from then.....

I do. And if this is the case, then you are back on the schedule you are supposed to be on so I would not worry. Nitrites can drop almost instantly as well as the ammonia so I would say you are on track.
