I have had an undiagnosed illness in my QT and a casualty. I have removed the body and done a 50% w/c. I know I can use bleach or alcohol but I'm not clear on the method. Do I soak in a bleach solution? At what ratio and how long? do I just wipe the equipment down with alcohol? What about my syphon hose? I don't want to pass this to my other tank or reinfect the QT.
