I am picking up a porc puffer from lfs tonight and am wanting to qt it. I have never qt before and am worried I will mess it up. I have a 20 gallon tank with hob power filter and ammonia badge. I was going to use water from my display tank with some prime. Would this work to keep ammonia down. Do I need to do water changes weekly on it. What do I treat with and for how long. I’ve heard porc puffers aren’t very tolerant of copper so maybe tank transfer method but can I set a qt tank up today for a fish tonight or is the time not enough to cycle? Thanks in advance.
