Other similiar readings at this stage of your cycle have been labelled as a Cycle Stall, i had three of them.
I would suggest a 50% water change with warm, de-chlorinated water.. monitor the ammonia and NitrIte for a while then probably re-dose to 2ppm.
Yeah, that is kind of what I figured, because week or so ago, I was clearing both ammonia and nitrite within 12 hours... I just did a 50% change, so I will test my parameters again in a few hours. I tested ammonia this morning (about 14 hours after the 2ppm dose, and it was still at about .25ppm. I tested right before the WC and it was at zero, so again, it was about 18 hours before it cleared completely. Hopefully after this wc, it can go back to clearing with 12 hours again, and stay that way for another week or two!
