I wanted to report as well. I have an ADA 60P so I calculated the actual tank volume to be 12.5 gal. I dosed 70 mL of H2O2, with 320 gph of flow that I redirected multiple times for 15 minutes, 60% water change, then dosed 5 mL of excel. Death count? 3 otos and 5 ember tetras. I don't know what I did wrong, I really don't like killing fish
