Unfortunately, I can't use my QT tank just yet. I am setting it up, about week 2, but it still isn't cycled yet. Been using seeded material, but still waiting. I want to introduce more seeded material but I don't want to grab ich from my aquarium and bring it to my QT tank.
See if Seachem Stability will work for you in seeding the media, since it sounds like you are doing a fishless cycle.
