😭 My 20 gallon crashed. Seven of my fish died overnight (Neons and Corydoras). I suspect a contaminate of some sort from grandkids. I can't prove it, but everything was fine when I went to bed, and the kids were in my room when I woke. Water parameters are zero ammonia and nitrite, 20 ppm nitrate, and 7 pH. One lonely Black Neon holding its own after a 80% water change.
