    For those keeping score at home, the ER thread is over here: http://forum.simplydiscus.com/showthread.php?133466

    As mentioned above, the symptoms seen above turn out, it seems, to have been nitrite-related. (Learned something there, that's for sure. Maybe this will help somebody else cycling on the fly, or going through a mini-cycle if they lose their filter bacteria.) I'm waiting for my methylene blue to show up tomorrow, but in the meantime have been using 4x the normal dose of Safe and some kosher salt with my daily water change, and the fish are doing better than they looked above. One of the smaller ones still darkens and hangs out with less appetite than the others, but I'm hoping the methylene blue, some time, and some clean water should help him get back to being himself. Didn't test the water today, but as of yesterday I was finally seeing some significant nitrates, so hopeful that the tank may finish cycling quickly. Crisis averted!

    Thanks, Mauro (a few days late!).

    Overall, fish are doing pretty well, as I continue working to manage the nitrite situation as described above. After consulting with Al I decided not to dose the tank as a whole with methylene blue, as the product info indicates it would set back the biological filter. What I did instead was to drain the main tank for a water change, and when the level was low I pulled one of the smaller fish who has been the most sullen and dark of late and gave him a 10 second dip in approximately a 50 ppm methylene blue solution. (He evacuated at once upon return, and seemed to lighten up a bit. Otherwise, jury's out on the effect, and his long-term prospects.)

    So, I'm continuing to watch the tank and I'm using a little salt and a lot of Safe when I do water changes and when I see signs of irritation or darkening that seem concerning. (They are more likely to show some of this when food is added to the tank, I've noticed, which is consistent with Al's theory about depleted O2.) On Al's advice, I decided that if several fish still weren't looking good I would pull the biomedia and keep cycling it in a bucket with pure ammonia and then go with just aeration, water changes and methylene blue. So far it doesn't seem like I need to go that route.

    However, the fish I dipped may be dealing with some hex or the like slowing him down, as I see some white poop out of him, and decreased appetite. However, he's still eating, so I'm just keeping an eye on him for now. He doesn't look too bad in this video from last night. I may try a little more salt and raising the temp a bit if he doesn't come all the way back soon.

    I'd say my experience with the group has left me a little less sanguine about the idea of adding fish before the biological filter is well-established. Even with big water changes there is a significant bio-load to contend with over the course of a 24-hour period. Safe is a great product and I think it has saved me here, but I'd rather not be relying on it to stave off toxicity. Lesson learned!
