Re: the ENDLESS tank cycle... Well, the good news is that it looks like you are near the end of your cycle. *Since you are already showing a nitrate level, that means that the bacteria that converts nitrites to nitrates is starting to form. *Water changes do not really affect your cycling time. *The majority of the bacteria that you are establishing in your cycle will be growing on your filter media, gravel and tank decorations. *My cycling experiences have normally taken 5-6 weeks and I always do water changes to keep ammonia and nitrites at safe levels for the fish. *Danios are a hardy fish, and making it through the ammonia spike is the hardest part of cycling with live fish, in my opinion, so you've done great. *You can keep the nitrite levels down by water changes every other day (or more often if needed) and watch the fish for signs of stress. *I have a feeling though, that your cycle will be completed soon - your nitrite-to-nitrate bacteria just need to get a little better established and you're on your way. *Keep us updated and good luck! |
