I didn't do a water change, but I did skip the ammonia dosing. The ammonia went to 0, nitrites have not moved from 2ppm no matter what I do. Haven't checked nitrates since Fri (been sick and had gout since the weekend so I've been a little lax). I'll check all params tomorrow. If I see 2ppm nitrites again tomorrow, I'm tempted to do a sizable water change just to see if that number changes at all. I'm sick of seeing 2ppm, it's the bane of my existence these days. I'm curious to see if the water change would drop it below 2ppm and then if it will go back to 2ppm after a day or two.
