On my previous set up I never had a Quarantine process. With my new set up I am going to have a QT but it’s all new to me. I do not want to keep the QT set up all the time so I was planning on keeping a small sponge filter running in my sump all the time and then transferring it to the QT tank to seed it when I need it. The part that I don’t understand is what I do with the sponge filter after the quarantine process? I want to keep it in the sump so it’s ready for the next time I need QT but I don’t want to risk infecting DT right? Is there a way to sterilize it before placing back in sump?
