Aquarium Advice Regular
Hi all, I'm planning on starting a community tank sometime soon. I'd really like to quarantine all fish before I put them in, but I'd like it to be a steady adding of fish without a big huge gap in between. So if I quarantine new fish for 2 weeks, and add them to my big tank, and then go out and buy new fish to sit in the quarantine...do I have to do anything to the QT tank beforehand? What if my last batch of fish DID have a sick one and had to be treated? Even if I treat the whole QT tank, does anything linger on any surfaces that could affect future fish that get put in?
