Hey fish lovers! I recently purchased a 10g tank for my QT/Hospital tank and was wondering how to keep it cycled without fish in it? I put some media from my established tank in it to get it running and have a HOB biowheel filter. Is it okay to keep it running all the time without fish in it? If not, what is the best method for this? I just want to be able to have a cycled tank ready in the event I need it. Any suggestions would be appreciated!
