I've got nitrites, finally. Thanks so much for the advice to take my lights off. After doing that, I dosed my tank (because there was not any ammonia) and within a day that tank's water cleared up and today, the nitrites are increasing.

So I have my Ammonia at about 2.0 right now and the nitrites are sitting pretty at about .25. I have to go to work for the next 6 hours, will the ammonia completely convert before then? and if so, should I dose a little bit of ammonia?
