So update to my bad losses after the Texas snowstorm. My 29 fish were in a 20 gal for emergency for the last 4 days (were in a 10 gal for 3 days prior) The water just came on allowing me to set up the tank. I had the filter from the 65 running on the 20 gal while they were in there to get the bacteria up and running again. (Added an insane amount of Turbostart to help the colony) Since my 65 was still water for 4 days, with 3 days prior with dead fish in it (total of a WEEK with no movement or aeration) the water was bubbly and foamy and had around 6ppm ammonia along with an insane amount of nitrates and nitrites, I ended up doing a 100% wc. My fish were struggling in the 20 gal so I moved them into the 65 when I got it running, along with adding more Turbostart. My reading is currently 1ppm, about an hour into it running again. I hate to do a fish-in cycle but I had no choice. Will my fish be okay while the bacteria adjusts? I will check again tomorrow and see what the levels are. Please let me know yalls thoughts!
