We had a black beard algae problem and decided to break our 75 gal tank completely down and start over. We set up the new tank with a new filter, and cleaned rocks. The temp was 78, no nitrates, no nitrites, ph at 7. Put 6 silver dollars, 3 turquois rainbows, a red tailed shark,and bottom feeders. Striped Raphael, blue crawdad, stick catfish, golden algae eater. All 6 silver dollars and 2 of the rainbows died overnight. All of the bottom feeders and the shark were fine. What did we do wrong?
