Water tests this morning show 0 nitrites and .5 nitrates, 7.6 low ph and 7.4 high ph. As far as ammonia, it is never at the pure yellow that is on the API test chart, but I have tested it against tap water and it is the same. I have also taken to get tested an a local pet store and they said it was fine. I also use Hikari Ultimate water conditioner after being told by them to not use Prime because it is sulfate based. I also use a Seachem Ammonia Badge that never leaves the safe zone. The 30% daily water change as well as the daily Ultimate dose should bind any ammonia even if there was a slight bit, I would think. Two of the loaches are looking a bit better, possibly, but the 3rd is looking worse (included in the photo) and I am guessing only has a few days left. The last one that seems to have passed (because I have not seen him in 3 days now) was the first loach put in the tank and the first to show ich. As far as the other inhabitants of the tank, there is a King Kong Parrot, a blood parrot, a polar blue parrot, a pink convict, two red devils, a green terror and a gold severum, a bristlenose pleco and a polka dotted pleco. Stress level seems to be low in the tank, with the King Kong doing a bit of chasing, but no attacking, and none of the fish bother the loaches from what I have ever seen. It seems like my options would be to stop all treatment and just sacrifice the loaches, which seems inevitable at this point, or keep using ich-x, which I feel cannot be good for the other fish long term. I believe I started the ich treatment on the 16th or 17th of March. My biggest worry about stopping treatment is if it will jump to the other fish, but it almost seems that they are immune from it? None have showed a sign at all of it and I am thinking that the ich was already in the tank when the first loach was added, but will only attach to the loaches. I could also do what Hikari suggested and quit the ich-x and try Prazipro. I also have a bottle of Kordon Rid Ich Plus I could try switching to, but just not sure another medication would be helpful or safe to the other fish after going through already weeks of treatment.
