Everything is testing right where it should. My tap has ammonia but luckily I cycled this filter to insane capacity, and it clears my tap water in 6 hours. I use Prime. We overdosed a little yesterday just in case. Since I bought the 6 apistos together form the same source and one died within 3 days, this one is flicking, and the other hovering...maybe they were already sick? I just don't have experience on guessing at the problem... I don't what to do.
I worried at first that I cross contaminated ich from my other tank, but I realllllly doubt it. I have been running scalding water through everything and letting all nets and tools completely dry out.
The kuhlis don't have any physical signs of a problem and neither do the apistos. No red gills, spots...etc. Just the flashing.
