I have a marineland magnum 350 pro with bio wheels running on my 55 gal FW tank. It only came with charcoal for filter media so I decided to swap out half of it for biomax. I am fully prepared for a mini cycle but I am hoping it doesn't last too long. The only occupants in the tank right now are 5 blue giant danios. I also added a second filter to help with water movement today. It is a fluval U3 internal filter. After cleaning the tank I noticed that I really needed something to help with water movement and I'm broke so the second filter is bring used more as a power head than a filter. Plus I am going to need to set up a QT yank soon so hopefully by the time I save up enough money for new fish and new power head I will be able to take my established filter and stick it in the 30 gal tank I have for future qt. do you think my main tank would go into a mini cycle when I pull out the second filter? I have read several threads where people have two filters running on tanks and pull on for their qt tanks. My second question is if you have to use your qt tank for sick fish, how do you put the filter back onto your main tank without contaminating that one?
