Hey guys so Im trying to set up a quarantine tank since my display tank had velvet. I lost 4 fish about 3 months ago and I only have 1 firefish left in the tank now. The part I'm confused about is, I read that most people seed a filter/sponge/marine block in their main tank to use in the quarantine tank to help it cycle, but since my display tank has velvet can I still do that? I plan on doing a 76 day fallow period to kill off the velvet while I quarantine my new fishes along with my filefish that survived the velvet outbreak.
