Ok, so my nitrites are going down. I was at the fish store yesterday, and the guy said that the nitrites would probably be high for only a week or so. I checked yesterday and they were down from 2.0ppm to 1.0ppm! Today, they are down to .50ppm! Ammonia still at 0ppm, so all is looking good. The bad news is that my black skirts seem to be reaching the end of their rope with this whole cycling process. They are looking very listless today. They have the occasional spurt of energy, but besides that, they just sort of hover in one spot most of the day. I'm worried that they won't hold on and turn back around to their former fun & happy selves. What did I do wrong? I've done everything so particularly this time around, I've absolutely obsessed over these little swimmers. Do some fish just not handle the cycling very well? Danios were recommended to me as first fish, but the fish store was out of them when I was there, so the guy said these black skirts would do well also. One thing was that I added Stress Coat today, instead of Aqua Plus (which was what I was using before) with my water change. I'm so leery of all these chemicals, and it seems whenever I add something new or different, things go from bad to worse. Needing some encouragement and advice here........ do you think they'll make it? If they don't :'( must I start again from scratch with this aquarium, a whole 'nother cycling process?
