Hi, I am new to this forum but have been researching on here for a while now. I need to set up a hospital tank to combat MI. I didn't have a QT established before this. I understand that I can use water from the DT to start, but was wondering if it would be acceptable to throw in a few bio balls from my sump to help get the bio filter established quicker in the hospital tank. I only have a couple of other sponge type filters in the aquarium and I have recently cleaned them so don't believe they would be of much help. I have read extensively on this forum and other sources (especially the very informative posts be leebca) so I believe I understand what all I must do. I I was just wondering about the bio balls specifically being used to help jump start my hospital tank. Thanks in advance for any help!
